I have had 3 HHMI Fellows since I joined the Tech faculty in 1997: Jaclyn Canas, Nick Miersma, and Christina Freitag.   I have had science teacher interns (Suzy Dunnum, Marianne Dobrovolny) as well as high school students.  I have also had undergraduates from the Honors College working in my lab. I do not currently have undergraduates working in my lab (but I'd like some).
I look for students with good backgrounds in biology AND chemistry. Conducting research at the undergraduate level also requires a good attitude and the ability to be flexible.

Fate and Effects of Nanomaterials (Fullerene, C60):
Organic nanomaterials have widespread applications which are likely to increase exponentially in the future, so it is critical to characterize the exposure potential of these emerging applications as early as possible.  Our objective is to determine critical environmental fate and transformation capacities of engineered nanomaterials using unmodified C60 (fullerene) as a model compound.  This project follows the paradigm of environmental fate studies for pesticide registration and the advantage of using radiotracers (14C-labeled compounds) in environmental chemistry studies.  We will determine partitioning behavior (Kow), soil (aerobic) and aquatic (aerobic and anaerobic) metabolism, adsorption-desorption, and phototransformation of uniformly labeled 14C-C60.  Our rationale for these relatively simple studies is that the determination of this basic environmental chemistry information on C60 would provide a strong scientific framework upon which to establish appropriate environmental regulations.  Our rationale for following the pesticide registration paradigm is that regulatory agencies, including EPA, are familiar with using this type of environmental data in exposure and risk assessments and in modeling programs such as PRZM/EXAMS.  At the completion of this project, it is our expectation that we will have characterized some of the basic environmental chemistry (fate, transport, and transformation) processes for C60.  The primary impact of our anticipated findings would be filling data gaps related to the transport and transformation (exposure) potential of C60.

Organochlorine Contaminants in Reptiles:
Most industrialized countries have imposed restrictions on the use and disposal of organochlorine (OC) pesticides. However, regulations governing the production, distribution, and use of chemicals in many developing countries are scant or inadequately enforced. DDT is still easily available in many South Asian countries and is reportedly still used for pest control in some countries in Central America. Despite the high use of pesticides and other chemicals in developing countries, few studies have been conducted concerning exposure and response of tropical wildlife to these compounds. My group conducts analyses of various tissue samples (eggs, fat) from crocodiles and alligators in order to better characterize to exposure of these organisms to OCs. We work with other scientists that are determining the effects of that exposure.

Brashears, Mindymindy.brashears@ttu.eduTTUAnimal Science & Food Technology;AFS 202Research;
My laboratory has trained undergraduate students from the Animal & Food Sciences, Biology, Microbiology, Engineering, and multiple areas of discipline, with techniques in microbiology and studies related to food-borne pathogens. We generally have 6-7student workers, in our laboratory, many of whom assist graduate students and technicians with numerous projects.  In the past I have been a HHMI mentor for students and would enjoy the opportunity to do so again.The focus of our laboratory is on food microbiology, and specifically food-borne pathogens. We currently have studies on methods to reduce the prevalence of pathogenic organisms, such as Escherichia coli 0157:H7, Salmonella species, Listeria monocytogenes, etc. in pre- and post- harvest conditions. Alternative methods to inhibit pathogenic organisms, using probiotic organisms, are a major area of research for our laboratory. Additional studies include, evaluating the prevalence of antibiotic-resistant pathogens, and potential transmission methods within livestock populations and methods to contain or reduce resistance patterns; vectors for food-borne pathogen transmission; mechanisms of pathogenesis and virulence to inhibitory agents, used in pre- and post- harvest products. Our laboratory has collaborations within the faculty of Animal & Food Sciences, including the International Center for Food Industry Excellence (ICFIE, Director Dr. Mindy Brashears), TTUHSC, USDA, multi-state, and international collaborations. Our current funding for ICFIE is in excess of 6 million dollars, which include collaborative projects with our laboratory. Our lab consists of 15 graduate students, 5 undergraduate workers, 3 technicians, and 2 post-doctoral senior research associates along with a reseach assistant professor.
The research opportunities available are focused on antimicrobial interventions to control food borne pathogens in meat products.  The focus will be on investigating metchanisms of inhibition of pathogens and also the physiological changes that occur within the pathogen itself to allow it to adapt and survive after exposure to interventions.

Stress and eating:
We are currently investigating how stress hormones interact with specific brain areas to influence feeding and appetite.
The influence of environmental contaminants on development of the endocrine system:
We are investigating the influence of various environmental contaminants on the development of the endocrine system in amphibians. We study amphibians because there are concerns that worldwide populations of amphibians are declining. Also, amphibians are a sensitive indicator species for potential effects on the health of humans and wildlife.

Proteolytic processing in reproduction and cancer:
The broad focus of my lab is to study the role of the novel cystatin, CRES (cystatin-related epididymal spematogenic) protein in reproduction. CRES represents the defining member of a new subgroup within the family 2 cystatins of cysteine protease inhibitors. The CRES subgroup members are characterized by lacking the same two of three consensus sites for cysteine protease inhibition and by their reproductive-specific expression. In vitro CRES does not inhibit cysteine proteases but rather inhibits some members of a family of serine proteases known as the prohormone convertases (PC). PCs selectively process precursor proteins including growth factors, receptors, and signaling molecules at dibasic sites resulting in functionally active proteins. Support that PCs play critical roles in normal cellular processes is evidenced by severe phenotypes observed in PC knockout mice. We have recently determined that CRES inhibits PC4, a convertase with restricted expression in the reproductive tract. PC4 knockout mice are infertile suggesting that critical sperm fertilization proteins are not processed in these mice. We are currently examining the role of CRES in mediating PC4 function in the reproductive tract to ultimately provide better therapies for infertile men as well as provide novel sites for male based contraceptives. Another and more recent interest in our lab is studying the role of PCs in tumor initiation and progression. Studies have shown that PCs are upregulated in several cancers including lung, brain and breast cancer. Because PCs activate a variety of proteins implicated in cancer including IGF-1, TGF-beta, and ADAMs, targeting PC function may be a novel approach to prevent tumor progression.​

We study functional amyloid in the reproductive tract.  Amyloids are self-aggregated proteins with a specific cross beta sheet structure.  While typically associated with neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, recent studies suggest that amyloid structures may also exist in normal cells and carry out biological functions.  Understanding how functional amyloid formation is controlled to avoid pathology will provide critical insight towards treating diseases where amyloid formation is not controlled.  Specifically, we have shown that the cystatin CRES forms amyloid in vitro and recently have shown that it also forms in vivo within the epididymal lumen.  Studies are currently in progress to study the mechanisms of CRES amyloid formation including how pathology is avoided.

Molecular systematics, population genetics and comparative genomics of lower vertebrates:
Our lab research interests are in vertebrate molecular systematics, population genetics and comparative genomics. Currently, we are studying the evolution and phylogeny of the Crocodylia in collaboration with Dr. Chris Brochu from the University of Iowa. This NSF-funded research is finding new molecular and morphological markers to generate the most comprehensive phylogenetic assessment of any vertebrate order yet attempted. Our recent 5-year research project dealing with the genetics of Morelets crocodile populations in Belize was highlighted in National Geographic Magazine (March 2007). A comparable large-scale study is being conducted to study the phylogeography and population genetics of the wide-ranging American crocodile, with the ultimate goal of establishing a pattern that will allow the crocodiles to be both a sustainable resource and protected in the wild. Work by former TTU/HHMI scholar Jeremy Weaver has revealed the presence of genomic interactions between the American and Cuban crocodiles, apparently due to signifiicant levels of hybridization. Using both mitochondrial and nuclear markers, we are also studying the relationships and population genetics of African Dwarf crocodiles. Finally our lab at TTU is now part of a research consortium from Mississippi State University and the University of Georgia that will be involved in the high throughput sequencing of 3 complete crocodilian genomes.

An HHMI Science Education Fellow worked in my lab for one summer. He created a fish collection from specimens caught on the summer research cruises, and participated in an age and growth study of fish using ear bones. He really enjoyed identifying all the strange fish and crabs brought back from the cruise! He continued to do undergraduate research in my lab for the next two years, and will be a coauthor on the fish age and growth paper when it is published.

I have had more than 20 undergrad research assistants (non-HHMI) in my lab. I try to provide them with the background and knowledge to understand the project and their part in it, and I encourage students to be involved at all levels, including the data analysis and writing. Our undergraduate workers are encouraged to participate in lab meetings, and they come with us to meetings of the American Fisheries Society if we can afford it. The more involved a student is, the more we all get out of it!
Prerequisites - A basic introductory biology or ecology course such as Populations, Communites and Ecosystems, and some basic knowledge of computers or stats would be most helpful. However, a willingness to learn and work hard, and an interest in marine science can substitute for these requirements.
Locating potential sites for marine reserves in the Gulf of Mexico:
We are using long-term data sets to locate potential sites for marine reserves (no fishing areas) in the Gulf of Mexico. We are interested in delineating communities, finding areas of high biodiversity, finding areas where important species overlap, and looking at changes in the abundance and distribution of marine species over the last 20-30 years. Students can participate in statistical or GIS analysis of the data, including creating and using ecological indices and learing the techniques of making maps from ecological data. Students will be encouraged to participate in research cruises aboard National Marine Fisheries Service ships to collect fish/invertebrates and to do an independent research project using the long term datasets, or the field collections.
Age and growth of marine fishes:
We are using the ear bones of marine fish to estimate their ages, growth rates, and birthdates, and to investigate significant life history events. This project involves lab work including epi-florescent microscopy and image analysis. I have recently obtained ear bones from Atlantic croaker that were caught in the 1970s, and students will be able to use these to make comparisons of growth rates over time and over different locations in the Gulf of Mexico. We also have a collection of red snapper, and students will be able to assess the ages and growth rates of red snapper caught off the Texas coast.
The physiological effects of catch and release fishing on red snapper:
We are currently studying the effects of catch and releas of undersized red snapper (a deep-water marine species) on their physiology, behavior, movements, and reproductive physiology. We conducted a controlled field experiment by catching red snapper using hook and line, taking their blood, then holding them in cages under oil platforms to check their survival for one week, and we currently are seeking a student to help us with data analysis and manuscript preparation. We have also spent several summers riding aboard commercial and recreational boats and taking blood from all fish that are thrown back to estimate their survival. We have constructed hyperbaric chambers and have red snapper living in tanks here at TTU to conduct experiments on the long-term physiological and ecological effects of catch and release of deep water fishes. An HHMI student working on this project will be able to participate in field collections, conduct lab analyses on the fish blood, conduct tagging experiments, or conducting other physiological or behavioral studies in conjunction with our field and lab work.
Tracking fish movements using the microchemistry of ear bones:
We are starting a project to use the chemicals incorporated into the ear bones of fish to track their movements and to determine whether fish move freely between environments with very low oxygen (hypoxia) or normal levels of oxygen. We will then compare the growth rates of fish in these different oxygen environments. This study is important for assessing the effects on fish of pollution and excess nutrients that cause hypoxia in the Gulf of Mexico. A student would initially prepare the bones for analysis, then use a machine that shoots a laser through several spots in the bone, vaporizing the material and sending it through an inductively-coupled plasma mass spectrometer (ICPMS) that analyzes the chemical structure.
Investigating the decline of Steller~s sea lions by investigating their prey:
We are using several new techniques to investigate why Steller's sea lions, an endangered species in Alaska, are declining. We are analyzing the fish bones contained in sea lion scat to assess changes in prey availability, distribution, and abundance, and to investigate the presence of contaminants in the prey. We are also planning to analyze the chemistry of fish bones collected from fish to see where the fish were eaten, and we are experimenting with techniques that can tell us the age and sex of the sea lion that created the scat. There are many opportunities for independent work on this project. Students could experiment with techniques to assess contamination or work with other fish parts such as eye lenses to identify prey species.
Exotoxicology and Marine Species
We are investigating the effects of triclosan, a widely used anti-bacterial product, on marine species.  Preliminary tests have shown that triclosan has effects on fish behavior, which may impact their ability to avoid predators and find prey.  Other behavioral changes may impact their ability to interact with con-specifics.  The increasing amounts of triclosan in the environment may have unintended consequences for fish and marine communities.

Immune-privileged Sertoli cells (SC) survive long-term when transplanted across immunological barriers, as allografts. In addition, they prolong the survival of co-grafted pancreatic islets when transplanted in diabetic mice. As antibody-mediated (complement) cell lysis plays an important role in chronic allograft rejection, we hypothesized that SC survive and protect co-transplanted islets by inhibiting antibody-mediated death. To test this, grafts collected at days 30 to 100 from successful and rejected SC/islet co-grafts will be analyzed for antibody deposition (IgG and IgM) by immunohistochemistry. Further, to look for complement deposition, grafts will be immunostained for complement factor 4 (C4, early complement activation marker), complement factor 3 (C3, middle complement activation marker) and membrane attack complex (MAC, final pore for cellular lysis). Results will be compared between the successful and rejected grafts to determine whether inhibition of antibody-complement mediated lysis by SC is important for chronic allograft protection. Results from this study will identify mechanisms important for SC graft protection, which in the long-term could improve survival of transplanted islets as a treatment for diabetes.

I have had the experience during the past ten years to mentor many different students. This includes master, Ph.D., or SABR students.

Our laboratory is specialized in Molecular and Cellular technologies, applied to the prostate cancer research field.

The Scholar should be a highly motivated individual with, if possible, a previous experience in c
ell culture methods and standard molecular and cellular techniques (i.e. cellular transfection; Gene reporter assay; RNA-, DNA-, and Protein- extractions; RT-PCR; Northern blot; immunoprecipitation; Western blot; zymography; reverse zymography; and immunohistochemistry). The scholar should also accept to work with mice as prostate cancer in vivo model. 

Macrophages have been described as one of the main inflammatory components involved in prostate cancer (PCa) initiation, progression and metastases formation. PEDF (Pigment Epithelium-Derived Factor) is an anti-angiogenic factor with differentiation activities and was recently suggested as an immune-modulating factor. PEDF expression has been shown to be down-regulated in PCa compared to normal tissues. In previous studies, we have demonstrated that PEDF re-expression in PCa cells curbs tumor growth in vivo and prolongs the survival of tumor-bearing mice. Others have shown that PEDF expression increased the recruitment of tumor-cytotoxic macrophages into orthotopic MatLyLu rat prostate tumors suggesting a new way through which PEDF curbs PCa growth. While all of these results emphasize the anti-tumor properties of PEDF, the delivery of PEDF still remain challenging. The objective of the present study is to investigate PEDF gene therapy using bone marrow-derived macrophages (BMDMs) as a novel therapeutic modality for advanced PCa. Our central hypothesis is that PEDF expression will induce the migration and differentiation of BMDMs into a tumor-cytotoxic phenotype and, as a corollary, will block tumor growth and metastases formation, and prolong survival. We have formulated this hypothesis on the basis of our preliminary data that showed that PEDF stimulates the migration of monocytes/macrophages using in vitro chemotaxis assays and our immunohistochemistry studies that demonstrated a positive correlation between PEDF expression levels and macrophage density in human prostate specimens. The present proposal which will use subcutaneous and orthotopic preclinical models may potentially lead to development of improved therapeutic approaches to PCa.

This will provide a painless alternative to the current hypodermic needle-based vaccination method. The student recruited for this project will be given an independent project to characterize the microparticle structure and to work on the development of a process to fill the microparticles with a model vaccine.

In the process the student will gain knowledge in the field of drug and vaccine delivery and acquire technical skills in the field of microparticle-based vaccine delivery.

Godard-Codding, Celineceline.godard-codding@tiehh.ttu.eduTTU ReeseEnvironmental Toxicology;Reese Campus Building 555 101AAResearch; No Preference;

   Dr. Godard-Codding has extensive experience with undergraduate mentoring.  In the last 10 years, she mentored 16 students who participated in  Toxicology Research Internships that lasted from 1 month to 18 month.  12 students did their internships at the Woods Hole Oceanographic Institution while 4 students did theirs at the University of Southern Maine.  The work resulted in 10 presentations at National and International meetings (such as the Society of Environmental Toxicology and Chemistry); four reports including three to International Whaling Commission subcommittees; and one peer-reviewed publication in Marine Environmental Research.

   Dr. Céline Godard-Codding is  assistant professor at The Institute of Environmental and Human Health (TIEHH) and the Department of Environmental Toxicology at Texas Tech University.  Dr. Godard-Codding’s research interests focus on genomic and cellular toxicology, mechanistic toxicology, endangered wildlife ecotoxicology and conservation, and biomarkers.  Species of special interest are marine mammals and turtles.  Similar to human toxicology, only in vitro and non-invasive or minimaly invasive tools can be used in endangered species to assess the impact of stress caused by environmental pollutants. Therfore all the tools and techniques applied in Dr.  Godard-Codding's laboratory are similar to the tools used in human toxicology and medical  laboratories.

   Dr. Godard-Codding trained in biochemical and genomic toxicology at the Woods Hole Oceanographic Institution under the supervision of Dr. John Stegeman (Godard et al. 2000 and 2005).  She stayed at the Woods Hole Oceanographic Institution in order to complete a postdoctoral training in environmental toxicology focusing on cytochrome P450 and their use as biomarkers in endangered mammalian species (Godard et al. 2004).  She then expanded her training in cytotoxicity, genotoxicity and cell culture as a senior postdoctoral fellow at the Maine Center for Toxicology and Environmental Health at the University of Southern Maine (Godard et al. 2006).  During her postdoctoral trainings, Dr. Godard-Codding supervised the toxicology program of a 5-year worldwide marine research cruise sponsored by Ocean Alliance and mentored 16 undergraduate and graduate students, gaining extensive project management and mentoring expertise.

Research internships will provide training in toxicology, cell culture, genomics and molecular biology techniques.  A background in biology and a strong interest in toxicology are recommended.  An understanding of sterile techniques is preferred but not required.  Research topics will include creation of primary cell cultures and measurements of biomarker of cell stress using quantitative RT-PCR, functional genomics, proteomics, and enzymatics.

All the research described below is done on tissues collected non-lethally in endangered species and under appropriate permits.

-Project 1: Developing sea turtle cell lines. 
All sea turtles are listed as endangered. In this project, tissues are obtained from sea turtle biopsies or from tissues of stranded sea turtles through collaborative efforts.  Cell lines from these tissues are then created, maintained and characterized in the laboratory.  Our goal is to create cell lines from all organs and all species, and we have already successfully obtained several cell lines.  At this time, only one other laboratory has succeeded in creating cell line from one single sea turtle, thus this is a pioneering research effort

Project 2: Testing the toxicity of pollutants in sea turtles using the cell lines developed in Project 1, we are investigating the toxicity of selected pollutants in sea turtles.  This project focuses on assessing cytotoxicity (cell death) and genotoxicity (chromosome damage)

Project 3: Cloning and expression of biomarkers of contaminant exposure in dolphin and polar bear tissues.  We are interested in biomarker genes and proteins that indicate exposure and or sensitivity to environmental pollution.  We have access to dolphin tissues (collected from stranded animals) and polar bear blood (from wild animals) and have already successfully started isolating some biomarkers.  The current goal is to clone several novel biomarker genes of interest and then assess their expression.

 -Project 4: Identifying novel biomarkers of contaminant exposure in dolphins using proteomic profiling and organotypic culture
In this project, we conduct a series of exposure experiments using dolphin biopsy slices (obtained from stranded dolphins).  The slices are then processed for proteomic profiling studies in order to identify new biomarkers of exposure or sensitivity to marine toxicants.

Broadly, I am interested in how the physiological stress response influences organismal function, health, and life-history tradeoffs. Using animal and human studies, I aim to understand how stress-related differences at various biological levels of analysis correspond to differences in health, behavior, reproduction, and fitness. Currently, my research program addresses two complementary central questions: 1) how does variation in response to and recovery from stressors translate into functional consequences in organismal behavior, health, life history trade-offs, and fitness, and 2) how do organismal behavior, genotype, sex, life history stage, and trade-offs alter the physiological stress response.

We are seeking a student who is dedicated and well organized, enjoys children, has transportation, and is able to commit two mornings per week for two semesters.

The Early Language and Memory (ELM) Project investigates language and memory development in diverse samples of preschool-aged children. This year we are testing a new technique for conducting interviews with young children about events they have witnessed or experienced.  We will examine whether this technique helps improve accuracy in children’s recollections, and the extent to which any improvements also depend on a child’s language capacities, social skills, and qualities of the home and school environments.  Since young children are routinely interviewed in a range of settings, including child custody cases, cases of suspected maltreatment, and criminal cases, it is important that they provide accurate information. Hopefully, this research will contribute to that mission.



Researchers on the project take part in data collection, which is gathered in local preschools from multiple informants using multiple methods.  Children are assessed on various scales of language ability. Their memory for a staged event is measured using the traditional or new interview technique. Classroom teachers report on children’s communication skills and classroom behaviors. Parents report on demographics, family configuration, life events, and the parent-child relationship.


 This project is funded by a grant from the National Institute of Health (#R15HD065589-01). As such, it provides students with an outstanding opportunity to take part in high profile, cutting edge behavioral research while gaining experience working with children in school settings.

My research investigates the intersection of two broad domains of social psychology: 1) group processes and intergroup relations, and 2) attitudes and persuasion. Within these domains I investigate how social groups influence people’s self-conception, attitudes, physiology, and biology as they relate to health behaviors. The goal of my research is to integrate basic cognitive processes into social interactive processes, societal processes, individual process, and internal processes that explain individual health behavior.

Research in my lab has a broad foci on: 1) the role that group processes and intergroup relations play in risk taking, attitude change, and persuasion; 2) the motivational role played by self-uncertainty in attitude change, group behavior, intergroup relations, and self-conception 3) influence processes within and between groups; 4) the structure of self-conception and identity in group and intergroup contexts; and 5) on physiological and biological processes related to attitude change and group processes.

Molecular and Biochemical Regulation of Carbohydrate Storage in Poplar Species and Cotton:

1.  Study the mechanism of seasonal changes in carbohydrate storage and metabolism in the xylem (wood) cells of poplars, such as cottonwood and aspen under the co-direction of molecular biologist, Dr. Zhixin Xie.  These trees synthesize and store starch in living cells of the xylem during the latee summer and autumn.  In the winter, enzymes of starch synthesis decline, and the starch is converted to soluble sugars, such as sucrose, as the appropriate enzymes appear.  The biochemical and molecular control of these changes in enzymes is not well understood, yet the sugars are important to the new vegetative growth and new wood production in the spring.  Recent evidence on the initiation of wood production in the spring indicates the involvement of small RNA molecules that regulate the level of messenger RNA for a specific enzyme associated with cell wall synthesis critical to the formation of cells in the xylem.  Dr. Xie and I are interested in determining whether a similar mechanism may operate to control the rise and fall of starch and sugar synthesis.

2.  A related project concerns the synthesis of starch in the stem and root xylem of cotton during the growing season.  As other woody, perennial plants, cotton stores starch in living cells in its xylem.  Many agronomists believe that this carbohydrate storage robs the developing fruits (bolls) and their developing cotton fibers of needed carbohydrate, causing lower fiber yield and quality, especially during the latter part of the growing season.  My lab has evidence that the carbohydrate stored in the xylem may be valuable as a source of carbohydrate during environmental stress periods when photosynthesis is dramatically reduced.  It is not known whether reducing starch synthesis in the xylem would actually benefit cotton fiber yield and quality.  A goal of this project is to create transgenic cotton plants with reduced expression of a gene for an important enzyme of starch synthesis in the xylem to test for the importance of starch storage during the growing season in cotton stems.

Structure function studies of nicotinic Acetylcholine Receptors (nAChR): Nicotinic acetylcholine receptors are ion-channels that are opened by binding of ligands/agonists to the membrane spanning receptor protein. These receptors are abundant in the central nervous system and molecular targets for a variety of clinically used drugs. We utilize the following techniques to study the structure and function of these very dynamic proteins:
- Site-directed mutagenesis, and other molecular biology techniques
- Western-Blotting, and other biochemistry techniques
- Electrophysiology (Don't worry, easy to learn!)
- homology Modeling, and other modeling
- Heterologous expression
Structure function studies of the Proton Coupled Folate Transporter (PCFT): This protein is responsible for intestinal folate uptake into the human body. It also plays a role in uptake of chemotherapeutics into tumors. Similar techniques than for the above named research area are being used.
For both research areas there are several projects available to chose from, depending on the skills and interests of the potential student.

I was also a faculty at the UT Southwestern Medical Center at Dallas. Currently I am an Assistant Professor (tenure track) at the Department of Cell Biology and Biochemistry, Texas Tech University Health Sciences Center (since April 2016). During my career I have mentored many undergraduate and graduate students and researchers (18 total) at a number of different programs during my work at several Universities (several students were from SURF (Summer Undergraduate Research Fellowship Program) at UT Southwestern Medical Center, similar to SABR at TTUHSC; PhD program at Texas A&M University; PhD and MD/PhD programs at UT Southwestern Medical Center). I will also mentor an undergraduate student during this summer in the frame of the SABR program at TTUHSC. I was working in multicultural environment and mentored students and researchers from different countries (USA, New Zealand, Turkey, Sweden, India, Russia), so I have ability to work with and instruct culturally diverse students and researchers. I have experience in the lecture presentations, as well as laboratory practice and in mentoring undergraduate, Ph.D. and M.D. students in their projects. In addition to training student and researchers affiliated with my working place, I was mentoring visitors from other colleges and universities. For example, Andrey Rybalchenko from Texas Christian University (Forth Worth, TX) was a recipient of Summer Undergraduate Research Fellowship Program (SURF), Dustin S. Griesemer from Washington University (St. Louis, MO) was a recipient of QP-SURF program, Karl Enquist was a visitor from Department of Biochemistry and Biophysics, Stockholm University (Sweden). I was directly supervising these students during their research programs. Results of students’ projects guided by me were incorporated in publications and presentations at multiple scientific conferences, and the participating students and researchers became coauthors. For example, trained by me three students and one researcher became coauthors of our recent paper in Cell. I have 31 scientific publications and our results were presented at various international and national meetings and conferences (59 presentations), as well as during invited or selected talks (35 talks and seminars) at different universities and meetings around the world. Many students were coauthors in these publications and presentations.We have friendly environment in the lab and students with different levels of skills are welcome. We work with students on individual basis. We can accommodate students from different majors, although it is beneficial for them if they are connected with biology, biomedical or chemistry majors. The most important things are motivation and interest in science and research.

We study molecular processes that happen in human cells (protein synthesis, regulation of gene expression, protein quality control, etc.) and molecular basis of diseases associated with these processes. We have many different projects where students can be involved: gene cloning, microscopy, gene expression regulation, etc. The titles of the projects in my lab are “Molecular Mechanisms of Human Diseases”, “RNA/protein quality control in health and disease”, “Molecular Mechanisms of Translational Regulation”, “Protein Interactions in Health and Disease”, “Mechanisms of Protein Misfolding in Neurodegenerative Diseases”, and others. These projects involve purification of nucleic acids, proteins, gel electrophoresis of nucleic acids and proteins, PCR, qPCR, gene cloning, Western blots, transformation of E. coli, human cell cultures, microscopy, and other cellular and molecular biology techniques. We have friendly environment in the lab and students with different level of skills are welcome. We work with students on individual basis. The type of project will depend on the students’ interests, their time commitment and their experience. We can accommodate students from different majors, although it is beneficial for them if they are connected with biology, biomedical or chemistry majors.

There are several interesting projects available including examination of Leishmania exosome composition and roles exosomes play to promote infection. Leishmania co-exist with bacteria in the midgut of sandfly and we work on understanding what relationship they can have – beneficial or inhibitory and what is the molecular mechanism behind. We are also trying to understand how deficiencies in lipids can affect protein synthesis machinery in Leishmania and as result virulence. These projects involve gene cloning, purification of nucleic acids, proteins, gel electrophoresis of nucleic acids and proteins, PCR, qPCR, Western blots, transformation of Leishmania major and E. coli, microscopy, animal work and other cellular and molecular biology techniques. We have a friendly environment in the lab and students with different levels of skills are welcome. I work with students on individual basis. We welcome students who are motivated and inspired by science.

Inflammation: macrophage responses to pore-forming toxins

Inflammation is a crucial component of many diseases, regardless of whether they are caused by autoimmunity, pathogenic microbes, tumors, or even particles and chemicals. Inflammation is also necessary to develop robust responses to vaccines. This inflammation depends on the response of macrophages and other innate immune cells to pathogenic conditions.

The research in my lab aims to elucidate novel mechanisms of inflammation by studying the interplay and downstream effects of bacterial pore-forming toxins, which trigger inflammation, on macrophages. Streptolysin O is an archetypal pore-forming toxin that can directly lyse cells. Interestingly, macrophages can withstand high doses of toxin. At these sublytic concentrations, macrophages resist the damage and execute a pro-inflammatory pathway. Understanding what mechanisms are required for damage resistance will help us regulate the inflammatory response, as well as apply that knowledge to other diseases directly related to membrane damage, such as muscular dystrophies.

A second aspect of the inflammatory response is the mechanism through which macrophages alert the rest of the immune system and elaborate the inflammatory response. To accomplish this, macrophages utilize a complex called the inflammasome to promote cytokine processing and release. In addition to cytokine processing and release, the macropahges also commit suicide via the pyroptotic cell death pathway. Elucidating how macrophages switch from incredible resistance to membrane damage induced by SLO and other agents to dismantling this resistance and tearing their own membranes apart will help us understand the fundamental cell death and repair mechanisms that lie at the heart of inflammation.

Bat diversity of the Texas Great Plains

Bats are a key component of Texas ecosystems; they function as bioindicators and also control insect pest populations. As the number of conservation issues in Texas grows, it is important that we have systematic data on species in order to formulate management plans. Very little research has been done on the bats in the panhandle of Texas.  Work with Dr. Tigga Kingston and PhD student Marina Fisher-Phelps to collect invaluable data for bat conservation in Texas. Field surveys will mostly be acoustical but will include some mist netting.


2 student positions for TTU undergraduates are available for fieldwork in Summer 2012, with analysis in Fall 2012. Responsibilities are still being developed and are likely to change as the needs of the project develop but will include:

i)Provide support to PhD student

ii)     Participate in field surveys - acoustic recording of bats

ii)   Enter and check data in the lab, sound analysis

iii)  Contribute to development of literature library

iv)  Attend lab meeting (Fall and Spring Semesters)


The lab does not provide a stipend.


Selection Criteria: Skills include, numerical/database, writing and communication, leadership + team, academic ability, commitment. Prior experience of working with bats is NOT expected for the TTU undergraduate positions. Students prepared to commit to a 1+ years are preferred. Rabies vaccination is not required for the internship but is required for handling bats.



Student Opportunity with the Southeast Asian Bat Conservation Research Unit (SEABCRU) with Dr Tigga Kingston (SEABCRU Director, Dept Biological Sciences, TTU)

The SEABCRU (www.seabcru.org) is a network of individuals, organizations, and institutes committed to conservation research of Southeast Asia’s imperiled bat fauna. It was established in 2007, and in 2011 received funds from the National Science Foundation to enhance the network and to collate and collect data on the abundance, distribution and diversity of bats across Southeast Asia. The SEABCRU is organized into four teams focusing on i) flying fox conservation, ii) conservation of cave-dependent bats, iii) conservation of forest-dependent bats and iv) taxonomy and systematics. Each team is led by 2-3 experts, supported by 5 students (a mix of Southeast Asian and US PhD and undergraduates).

2 student positions for TTU undergraduates as part of the student support teams are available.  Responsibilities are still being developed and are likely to change as the needs of the SEABCRU develop but include:

i)                    Provide support to their team leaders throughout the year

ii)                  Enter and check data in the SEABCRU database

iii)                Contribute to and motivate discussions in the SEABCRU social network.  

iv)                Find and prepare news articles for the front end of the SEABCRU website

v)                  Contribute to development of literature library

vi)                Attend the SEABCRU network meeting in June 2012 (2-3 days) in support of their team leaders, and their team’s subsequent 3-day workshop in Thailand.

The SEABCRU does not provide a stipend, but full travel support to the meeting and workshops in Thailand is provided.

Selection Criteria: Skills (ICT, numerical/database, writing and communication, leadership + team), academic ability, commitment. Prior experience of working with bats or international travel is NOT expected for the TTU undergraduate positions; however, you must be comfortable working with a diverse international team, and be receptive to new experiences.

Fourteen other undergraduates (not part of HHMI) have also worked in my lab (primarily summers) since 2000.
Students should have an interest in and preferably some background coursework in ecology. Some projects involve fieldwork during summer session.
 Surveying the dragonflies and damselflies of the Llano Estacado:
Little is known about the diversity of odonates (dragonflies and damselflies) of the playas of the Llano Estacado, or how that diversity is impacted by human activity. The objective of this project is to survey adult and larval odonates at playas surrounded by different forms of human land-use. It is hoped that this information will be useful in identifying sensitive indicator species for water/environmental quality. No experience is necessary, but must be available in summer for field work.

Potential effects of projected climate change on dragonflies and damselflies:
Climate change is projected to increase air and water temperatures, alter precipitation regimes, and cause extended droughts. We currently have some lab experiments examining potential effects of warming and desiccation on the growth, development, and survival of dragonflies and damselflies. No experience is necessary. 

Analyses of dragonfly and damselfly metapopulations and metacommunities:
Based on the long-term data that my lab has collected over the past several years, this project would serve those students most interested in gaining database management and computer-based analysis skills. We have spatial and temporal data on both biodiversity and abiotic environmental variables. We are interested in determining whether the occurrence and abundance of certain dragonfly and damselfly species can be predicted by certain environmental parameters, which is crucial to identifying when organisms are experiencing environmental stress. Students involved in this project have a great opportunity to gain and use GIS, spatial modeling, and/or statistical skills. No field work is necessary but can be included for students interested in that aspect. This project does not necessarily involve summer field work.

I typically have 6-10 undergraduate research volunteers in my lab who are involved in a wide range of research activities from data entry, data collection, data analysis, presentation of data at state, regional, and national conferences, as well as manuscript publications. I have mentored scholars from the TTU Center for Undergraduate Research. My research lab focuses on translational/transdisciplinary studies of factors that influence health status during the aging process. Our lab conducts human studies only and has particular emphasis on the impact of environmental exposure on health status and how that leads to decline in mental abilities.

Experience with environmental exposures, in particular naturally occurring groundwater toxins. Experience conducting literature reviews through PubMed, Scopus, Ovid or other similar search engines. Preferred experience with human studies and knowledge regarding confidentiality and HIPPA issues. Interests in translational research projects and an ability to integrate into a transdisciplinary team.

My research lab has 2 ongoing cohort studies:

1.     Project FRONTIER is an epidemiological study of factors impacting the health status of rural-dwelling adults and elders. This is the most comprehensive rural health study in U.S. history and will soon also be the largest. In this study we examine a wide range of topics though one major emphasis on the impact of long-term low-level groundwater exposures on health status (e.g. presence of diabetes, hypertension, hyperlipidemia, cognitive impairment and/or dementia). We are also studying the link between cardiovascular disease and associated risk factors and neuropsychological status. Students have the opportunity to get involved with a wide range of topics through this study as well as take the lead on independent studies as they develop in the lab. Students also have the opportunity to gain experience conducting interviews and examinations.

2.     Texas Alzheimer’s Research Consortium (www.txalzresearch.org).  My lab is also the TTUHSC site for the Texas Alzheimer’s Research Consortium (TARC).  The TARC is a state-funded consortium that consists of 5 institutes across Texas (TTUHSC, Baylor College of Medicine, University of Texas Southwestern Medical Center, University of North Texas Health Sciences Center, and University of Texas Health Sciences Center – San Antonio). The TARC has a specific emphasis on genetic and biomarkers associated with Alzheimer’s disease. We have recently published a first-step towards the creation of a blood-test for Alzheimer’s disease and have also identified novel genetic mutations associated with disease status and clinical picture. Students have the opportunity to get involved with project as well and, after gaining experience in the group, can take the lead on projects utilizing this data. Students can gain experience observing or participating in research examinations that are standard part of Alzheimer’s disease diagnostics.

In general terms, my laboratory is mainly involved in applied research aim at improving fertility in both humans and animals. We currently have research going in six distinct areas:     Improvement of cryopreservation (freezing techniques for embryos. The research is looking at developing new solutions the problems of preparing embryos from species or breeds which currently have poor freezing rates.      Development of a unique collection system for human and animal semen. This is ongoing research with a patented device developed in my laboratory for semen collection. We are to the point of human trials and research is designed to collect data to allow wide spread use of the device in humans and animals.      Development of new media for the culture and cryopreservation of sperm, egg cells and embryos. Most media current used for these processes were developed for other cell types and may no be optimal for reproductive tissues. We are looking at new and unique compounds to improve this process.      A simple and inexpensive means of sex selection in semen. The is an obvious need in agriculture for sex section of semen. Current technologies are too expensive, therefore there is a need to find a cost-effective methodology. We are working with a technique developed in this lab (and under patent review) which has shifted the sperm ratio to 75:25 in laboratory tests. We are gearing up to conduct animal trial to see if this equates to the same ratio of male:females in a bovine model.      A basic understand of the biochemical pathways involved in preparing sperm for fertilization. Chemical, sperm are very simple cells. During development they “throw away” most of what an average cell has to react to its environment. We are trying to understand how it used its limited biochemical resource to accomplish the steps necessary for fertilization.      A basic understanding of the effect of electromagnetic fields on gametes and embryos in assisted reproductive laboratories.

·        CD4+ T-cells display an array of functions that can be traced to distinct lineages of thymocytes or to a variety of effector fates open to a naïve T cell. The path taken during thymic development and during activation in the periphery depends not only on signals received through the TCR, but also on individual signals received through other cellular receptors.  Earlier studies, beginning 20 years ago, showed that complement receptor 1 (CD35) exists on a minor population of human CD4+ and CD8+ T-cells.  To date, it has not been determined whether expression of this receptor marks a separate lineage of T-cells or the role this receptor plays during T-cell activation.  Thus, the long-term goal of our research is to determine the basis of CD35 expression on T-cells and the effect its complement ligands’ C3b and C4b have on T-cell immunity.  Understanding how the complement system influences T-cell activity is significant as it will further our basic knowledge of the interaction between innate and adaptive immunity and could be valuable in development of vaccines for autoimmune and infectious diseases, and in therapeutic treatments for various types of cancer.

>"Computational analysis of causality between microRNAs and antisense transcription" (This project was funded by the NIH from 2007-2010) Antisense transcription is a widespread and pervasive phenomenon affecting about 25% of eukaryotic genes, but its origins and functions are unknown. Small RNAs such as microRNAs (miRNAs) and trans-acting small-interfering RNAs (ta-siRNAs) are also pervasive in metazoans and play important roles in gene regulation, development, and disease, but to date the predictive power of computational methods for plant and animal small RNA discovery is limited. Based on computational analysis of Arabidopsis and rice transcriptome databases, it is hypothesized that miRNAs and ta-siRNAs are triggers for antisense transcription. This hypothesis will be rigorously tested using computational and statistical methods on the Arabidopsis, rice, grape and sorghum reference genomes and in emerging genomes such as cotton and other crops. Using known and hypothesized miRNA and ta-siRNA target gene antisense transcription as a learning set, a new algorithm will be developed based on antisense transcription combined with established miRNA prediction methods to discover new candidate miRNAs, ta-siRNAs and their hypothetical target genes. The identified putative small RNA target genes would be inherently “interesting” as potential key regulators of growth and development. The predicted novel small RNAs and their targets will be experimentally validated with a facile transient assay system, RNA blots and rapid amplification of cDNA ends to prove novel miRNA-directed cleavage of targets. Transcriptome profiling on whole genome tiling arrays of known mutants that affect miRNAs and antisense transcription will determine the extent of causality of antisense and small RNAs. A novel algorithm for small RNA prediction based on a phenomenon shared between plants and animals may have general utility for small RNA discovery in any organism for which deep genomic resources exist, for genome annotation, and for better understanding of human disease etiologies. Such a predictive tool would also have utility in the fields of functional genomics and evolutionary biology. A better understanding of small RNAs and their roles in gene regulation may shed light on "the RNA World" and the origins of life. >"Molecular genetic analysis of HARLEQUIN, a pleiotropic mutant of Arabidopsis that has ectopic expression of a hormone-regulated reporter gene and cell wall defects." (This work has been submitted to the DOE for funding) Plant cell walls are complex carbohydrate polymers that comprise the bulk of biomass on earth and are the ultimate source of fodder and fiber in agriculture, yet knowledge of their biogenesis and functions in signal transduction of environmental stimuli and plant development is quite limited, even in model organisms. We have isolated a mutant of Arabidopsis, harlequin (hlq), that has altered abscisic acid (ABA)-, stress- and auxin-inducible late-embryogenesis-abundant pDc3:GUS reporter gene expression in roots and guard cells and pleiotropic effects on epidermal cell morphogenesis and the cell wall. The HLQ gene will be cloned by map-based methods and its subcellular and tissue-specific expression characterized. Detailed phenotypic characterization of hlq cell walls by immunocytological, chemical and spectroscopic means will be carried out in reference to known cell wall mutants. The transcriptome of hlq will be compared with wild type and ABA- or IAA-treated tissues in order to identify the molecular events mediated by the HLQ gene and their relationship to hormone responses. Functional identification and molecular cloning of a novel gene involved in ABA-, auxin-, stress perception/responses and cell wall metabolism will lead to new insights into fundamental processes such as cell expansion and morphogenesis in response to environmental and hormonal cues. A major application of such knowledge will be to more fully realize plants' potential for biomass production and adaptation to more marginal environments that experience water deficits and high salinity. > "Functional characterization of pyrbactin-like abscisic acid receptors in transgenic cotton" The growth in the world';s population combined with a general increase in global prosperity and decrease in arable land are creating increasing demands for food, fiber, biofuels, and sustainable agriculture. More than 80% of available fresh water is consumed by agriculture (1). Drought is a perennial environmental constraint, affecting an estimated 25% of all crops and completely decimating west Texas dryland cotton yields on a regular basis. Estimates of the value-added worth of cotton with increased photosynthetic and water use efficiencies, enhanced flowering, and improved seed qualities exceed $200 million/yr in west Texas, $1 billion/yr in the USA, and $5 billion/yr globally (2). Abscisic acid (ABA) is a plant hormone that controls adaptation to drought, abiotic and biotic stresses, root and seed development, and cellulose biosynthesis. Receptors for ABA have recently been discovered and shown to confer drought tolerance in transgenic plants and to interact with protein phosphatases and transcription factors that we have been studying, ABA-INSENSITIVE-1 (ABI1), the cognate of a large family of protein phosphatases 2C, and the basic leucine zipper (bZIP) transcription factor ABI5. We have generated transgenic cotton that overexpress ABI5 and other transcription factors and have shown they improve vegetative and fiber growth traits. We are in the process of transforming cotton with the ABA receptors PYRBACTIN RESISTANCE1 (PYR1) and PYR-Like homologues and dominant-negative mutant version of ABI1 to provide insight into the role of ABA signaling in cotton growth and development and establish a proof-in-principle that we can engineer value-added stress response traits and improved seed and fiber qualities in cotton.

P. aeruginosa Pathogenesis and Biofilm Formation in Wounds

Infection with the Gram-negative pathogen Pseudomonas aeruginosa is one of the major causes of morbidity and mortality in severely burned patients, and the cause of debilitating chronic infections in diabetic patients. P. aeruginosa relies on an arsenal of cell-associated and secreted virulence factors to colonize and infect its host, and it persists and invades the immune system by building biofilms.  We have recently shown that P. aeruginosa forms biofilm in burn wounds, specifically surrounding blood vessels and adipocytes.  Currently, we are focusing on characterizing the biofilms formed in chronic diabetic wounds.  

Interkingdom Signaling between P. aeruginosa Quorum Sensing Molecules and Host Cells 

Quorum sensing (QS) is a cell density-dependent signaling process used by many bacteria to coordinate gene expression in a population.  QS in Gram-negative bacteria is controlled by diffusible molecules called autoinducers (AI) that function as ligands for regulatable transcription factors.  At least two separate QS systems exist in P. aeruginosa, the LasI/LasR and RhlI/RhlR systems.  The ligands for LasR and RhlR are N-3-oxododecanoyl- and N-butyryl- homoserine lactones, or PAI-1 and PAI-2, respectively. Several studies indicate that bacterial autoinducers, and PAI-1 in particular, can also influence gene expression in host eukaryotic cells, a process we’ve termed interkingdom signaling.  We hypothesize that this regulatory process involves autoinducer receptor molecules in the host cells, possibly transcription factors.  We have shown that P. aeruginosa autoinducers can efficiently enter mammalian cells and modulate gene expression potentially through the interaction of nuclear hormone receptors. In addition we have also recently shown that the nematode C. elegans can sense bacterial autoinducers and use this sensory information to ‘learn’ to avoid pathogens.

I have several research opportunities in my lab ranging from the use of mathematical models to understand/predict how species respond to anthropogenic disturbances. We also use a wide variety of invertebrate and vertebrate animals to better understand organismal response to environmental stress. We are also conducting experiments related to multiple stressors including climate change. There is some opportunity to do physiological and/or molecular biology related to response to environmental stressors. We have an ongoing project with the Lubbock Lakes system that may provide several interesting opportunities to work with fish, snails or other invertebrates.

Sizing up the Role of G1-phase Cdks in the Control of Cell Proliferation:
Genetic experiments have shown that G1-phase cyclin dependent kinases (Cdks) are required for normal proliferation and development. In contrast, hyper-active Cdks are implicated in the causation of cancer. However, the molecular mechanisms that modulate the activity of G1-phase Cdks are still not well understood. Thus, the broad and long-term goals of my laboratory are to identify and dissect the genetic, molecular and biochemical pathways that control G1-phase Cdk activity and to determine the role of G1-phase Cdks in controlling cell proliferation. Using yeast as a genetic model system, we have discovered a novel mechanism whereby G1-phase Cdk activity and cell proliferation are regulated. Namely, we have shown that G1-phase Cdk activity and the proliferative capacity of cells are strongly linked to cell size. Importantly, cells larger than normal are hyperproliferative due to elevated G1-phase Cdk activity. Interestingly, homeostasis is maintained because lifespan is also cell size dependent; large cells die considerably sooner than small cells. Because G1-phase Cdks and the basic mechanisms of cell cycle control are so highly conserved, we hypothesize that mammalian cell proliferation and G1-phase Cdk activity are also linked to cell size. Linking cell size to proliferation rate using G1-phase Cdks might represent a physiological means that enables large resting cells (e.g. oocytes or stem cells) to proliferate rapidly in response to stimuli (i.e. fertilization or differentiation/regeneration cues, respectively). However, the inability to appropriately down regulate G1-phase Cdk activity might be a cause of cancer.

Fire ecology and evolutionary ecology

Fire ecology of Texas savannas:

Historically, fire maintained open savannas in much of west Texas.  Over the last century, many rangelands have seen increasing densities of shrubs and trees and decreasing grass cover partly due to decreased fire frequency. My lab is interested in several basic questions of fire ecology in these systems.  How does winter drought (especially the interaction of water stress and freezing temperatures) affect resprouts and seedlings of woody species?  How do differences in flammability of different species influence interactions among them?  Can differences in flammability of grassland species help predict post-fire community structure?

Fire-stimulated seed germination in prairie species:

Many plant species in fire-prone regions show fire-stimulated seed germination.  In shrublands in California and South Africa, for example, there are species that germinate only when exposed to smoke.  Some of these species lay dormant in the soil for years between fires.  Here on the plains, tallgrass and shortgrass prairies experience frequent fires and fire is often used by managers in restoration.  Additionally some prairie species have been difficult to cultivate because of seed dormancy.  A former HHMI student in my lab discovered smoke-stimulated germination in several species.  We'd like to continue work in this area.

Metalloenzymes and Antibiotic Resistance in Pathogenic Bacteria:
ß-Lactam antibiotics (such as penicillins and cephalosporins) are the most heavily prescribed antibacterial drugs in clinical use today. In fact, three of the twenty most commonly prescribed drugs in the U. S. fall in this category. ß-Lactamases are enzymes that catalyze the hydrolytic inactivation of ß-lactam antibiotics and thereby constitute the major mechanism by which pathogenic bacteria become resistant to such antibiotics. Our research interest is focused on metallo-ß-lactamases produced by bacteria such as Bacillus cereus or B. anthracis. Not much is known concerning compounds that can inhibit metallo-ß-lactamases and thereby allow the antibiotics to do their job of killing pathogenic bacteria. Clearly, understanding the reaction mechanisms of ß-lactamases is of considerable importance to the pharmaceutical industry and the medical community. Our research approach involves site-directed mutagenesis of metallo-ß-lactamases, expression and purification of wild type and mutant forms of the enzyme, presteady-state and steady-state kinetic studies and spectroscopic experiments on the purified enzymes. We are using rational drug design and combinatorial chemical approaches to find new metallo-ß-lactamase inhibitors.

Biochemical Endocrinology of Insect Metamorphosis: (1) Functional Analysis of the Ecdysone Receptor:
Ecdysone, the steroid hormone that singly regulates the multitude of biochemical activities involved in growth, metamorphosis, homeostasis, and even reproduction in most invertebrates is considered as the true ancestral signaling steroid molecule. Hence the receptor for this hormone, ecdysone receptor (EcR), is probably one of the earliest eucaryotic nuclear hormone receptors. The fact that all the millions of species in the class Arthropoda, with an evolutionary history of ~ 600 million years, utilize ecdysone (E) to regulate their physiological functions, accentuates the importance of researching EcR’s function. Our studies on the mechanisms by which ecdysone and EcR regulate the varying and multitude of physiological events are expected to lead to a better understanding of how gene activity in higher eucaryotes is regulated by ligand/receptor complexes and how terpenoid ligand regulation of cell function has evolved. Vertebrate systems need several steroid hormones and other ligands (retinoic acids, thyroid hormone, vitamin D, etc), to regulate multitude of biological activities that are controlled singly by ecdysone . Ecdysone action is analogous to that of thyroid hormones, based on their regulation of varied and numerous cell functions, dimerization of the receptors with RXRs, and their involvement in metamorphosis. Ecdysone functions similar to the sex steroid hormones, estrogens and androgens, as it has gonadotrophic activity in both male and female adult insects. The consensus ecdysone response element (EcRE) of some ecdysone regulated genes occurs twice in a rotationally symmetrical fashion very similar to those of glucocoticoid response elements (GRE) in glucocorticoid responsive genes. Phylogenetic comparisons of gene sequences place EcR closest to the vitamin D receptor in the nuclear receptor superfamily dendrogram. Thus EcR is a fascinating protein for structure-function and expression regulation studies, as it should possess within its amino acid sequence the features necessary for exhibiting activities characteristic of several mammalian nuclear hormone receptors. Investigations on EcR structure, function, and activity regulation, are important areas of research, for students of endocrinology, developmental biology, and molecular evolution. Studies on E/EcR regulation of gene activity will define how steroid dependent hierarch of transcription factor expression, and the consequent protein-protein interactions, combine to signal either tissue development or differrentiation. The goals of our studies are to answer the following questions: (1). Does EcR use different response elements for gene regulation at different stages of development?, (2). How does EcR regulate gene activity in the absence of the ligand?, (3). What other proteins interact with EcR to account for differntial gene activity that occurs in a hormonal-, developmental-, and tissue-, specific manner?, and (4). What is the significance of time-, and tissue-, specific tyrosine phosphorylation of EcR that has been demonstrated. Molecular biological procedures that are in the forefront of present day endocrinological research are being applied to answer these questions.
Biochemical Endocrinology of Insect Metamorphosis: (2) Molecular Characterization of Juvenile Hormone Receptor:
The Juvenile Hormone (JH) is a remarkable endocrine secreted molecule due to its chemical nature and versatility to regulate a variety of aspects during insect development. Four decades of studies indicate that JH probably functions via a intracellular receptor. Definitive understanding of JH’s mechanism of action requires the isolation and characterization of the receptor for this hormone (JHR). Given that insects have evolved over hundreds of millions of years, while retaining the basic physiological, functional and structural features necessary for JH action, characterizing the JH receptor is of great theoretical and evolutionary interest. Once isolated and characterized, further biochemical and genetic analyses on the receptor should permit key tests on hypotheses concerning evolution of terpenoid hormone signaling pathways for regulating morphogenesis, metamorphosis and gene activity. Equally important, rapid development and deployment of species specific JHR antagonists for control of harmful insects will be possible thereby expanding the effectiveness of “ biological pest control”. The goals of our studies are three fold. First, use the silkmoth as a model system to isolate and characterize the Juvenile Hormone Receptor. Second, use the information on silkmoth JHR to initiate studies on JHRs of other insect species, the priority being given to Drosophila JHR. Third, define the structure-function relationships of the JHR molecule, especially of the ligand binding domain so as to design rational antagonists. The current aim of this projectl is to isolate and characterize the receptor for the Juvenile Hormone using silkmoth epidermis (which offers several advantages for these studies) as the experimental system. We will build on our initial success in developing a new affinity probe, and employ this probe for affinity purification, expression screening, and phage display selection in appropriate combinations to successfully achieve the stated goal. Antibody and cDNA probes will be used to follow JHR dynamics during development, and correlate the data with JH titer determinations.

C2 domains are fairly common protein motifs that link proteins to biological membranes; consequently, mutations in these domains can be extremely debilitating.  My lab examines the 3D structure of these proteins using X-ray crystallography to construct a high-resolution image of these mutant proteins with the intent to eventually cure the disease.

Our present interest is in the protein dysferlin.  Mutations in this protein causes Limb-Girdle muscular dystrophy in humans. The student's project will involve purification and crystallization of one of the seven C2 domains in human dysferlin.  If all goes well, the student will be able to collect high-resolution X-ray data on the resulting crystal at one of the major US synchrotron sources. Once the X-ray data is collected and the 3D structure calculated, the student could be the first to understand how specific mutations in this protein leads to disease.

Morphogenesis of the cephalic furrow. In this project, we study the cell shape changes and tissue movements involved in cephalic furrow formation during Drosophila gastrulation. During cephalic furrow formation, the cellular blastoderm invaginates into the embryo as a simple fold, retaining its epithelial character. We are investigating the morphogenetic processes and forces involved in remodeling the embryonic blastoderm during cephalic furrow formation. We are also taking a genetic approach to identify the genes that control this process. We have identified several genes and are currently analyzing their cellular functions. Regulation of microfilament dynamics during development. In this project, we study the role of actomyosin dynamics during cellularization, the process of forming cells in the multinucleate Drosophila embryo. During this stage of development, a lattice-like network of interconnected microfilament rings encompasses the entire embryo. We have found that src64 is involved in regulating the contraction of these microfilament rings. We are currently taking a genetic approach to investigate how nonmuscle myosin II is regulated during cellularization. Src64 signaling during Drosophila development. In this project, we study signal transduction by Src64, a nonreceptor tyrosine kinase homologous to vertebrate src.

ATP synthase: structure of the stator stalk

ATP synthase is the central enzyme of the energy metabolism in most organisms. It uses the energy contained in a transmembrane proton gradient to drive the synthesis of ATP from ADP and Pi. ATP synthesis and proton translocation are coupled by a unique mechanism, subunit rotation; electrochemical energy (proton gradient) is converted into mechanical energy (subunit rotation), and back into chemical energy (ATP). This makes ATP synthase the smallest known rotary motor, leading to potential applications in nanotechnology. The static, i.e. non-rotating, portions of the proton-translocation and the ATP synthesis/hydrolysis machineries are held together by the “stator stalk”. The precise structure of this stator stalk is not known. We are using a combination of genetic, molecular-biological, biochemical and biophysical methods to solve this structure.

Our goal is to understand gene structure and function, and how regulation of gene expression governs important properties using cotton trichomes/fibers as a single-celled model genomics platform. We recently completed sequencing of a cotton genome as an enabling tool for fundamental studies and agribiotechnology applications (trait development). In today's environment, research requires a solid knowledge of basic biology as well as computer skills to perform bioinformatics (data mining of sequenced genomes). At present, we are investigating epigenomics and how this level of regulation re-models the fiber transcriptome as a function of development. This work entails database searches and computer work before proving working hypotheses experimentally. So, dissecting the regulatory pathways and how gene expression is controlled to produce a particular trait or phenotype is an important aspect of our work.

Opportunies in my research lab run the gamut, from bioinformatics (computer analysis) of genes and gene families in developmental and evolutionary context, recombinant DNA/cloning, transient assays to turn off a gene and study the mutant phenotype, to computer/protein modeling.

I've served as a mentor for both HHMI and Honors College Undergraduate Research Fellows. Kelly Asbill continue her graduate education in plant pathology at Texas A&M.  John Gottula is currently in the Ph.D. program at Cornell University.  As an undergraduate student, I worked three years in my mentor&rsquo;s laboratory. Thus I have a firsthand understanding of the valuable educational and career opportunities this experience provides to the student. I am looking for students with a interest in molecular genetics, specifically; utilizing DNA based strategies to address basic questions in genetics, evolution, and host-pathogen interactions.

Bacterial blight of cotton, incited by the pathogen Xanthomonas axonopodis pv. malvacearum (Xam), is a classical example of a plant-pathogen relationship in an important crop. A 65-year history of research has led to our current understanding of both plant resistance of cotton and pathogenicity of the bacterium. The disease can reduce cotton production by an estimated 0.5 to 5% annually (Blasingame 2006). Considering the annual West Texas production of 4 million bales sold at $0.70 per lb, the annual loss in revenue to producers is approximately $6.7 to 67.2 million.

My long-term research goals is to (1) elucidate the genome organization of R-genes in both the diploid and tetraploid genomes, (2) pinpoint likely events (relative to Gossypium speciation) that led to the origin and radiation of R-genes in cotton, (3) define Xam population dynamics, (4) compare and contrast the sequence diversity among different R-genes and Xam Avr genes, and (5) examine host-pathogen interactions leading to host plant resistance and pathogenicity. The immediate project goals will address a “critical needto determine the DNA sequence that encodes the protein that confers resistance to all US Xam races (Specific Goal 1) and to examine the genetic variability among the Xam avrBs3 gene family (Specific Goal 2). I will focus this effort on cloning the most recently evolved bacterial blight R-gene (B12). The B12 locus has been fine-mapped to a region of 0.63 cM as part of a USDA-NRI Plant Genome Award (CSREES-NRI-2003-00696, PI Wright). A second specific goal will examine the function motifs among avrBs3 family members within an isolate then among four Xam races. The rationale behind this activity is to develop enabling tool to characterize Xam avrBs3 family members.  At the completion of this project I will elucidate the function and begin to unravel connections in regulatory gene networks implicated in disease resistance.

Have strong interest in molecular and cell biology research. We also welcome Technogy scholars who are interested in apply their computer programming skills in biology. Please feel free to contact me by phone or email if you have questions regarding the ongoing research projects in my lab.
Research in my lab is focusd on small RNA-mediated processes including post-transcriptional gene silencing, RNA-directed DNA methylation, and antiviral defense. We use Arabidopsis thaliana, a reference species for flowering plants as a central model system for our research. Please visit my faculty home page or stop by my office for further information.

I have mentored 26 undergraduate researchers at TTU so far and I have supervised two undergraduate honors theses. I also supervised one undergraduate student for TTU/HHMI in the past. I have supervised 7 master students and 9 PhD students for their thesis/dissertations.

​The general topic lies in human modeling and simulation. The objective is to simulate whole body human motion or part of bodies to understand why human move as they do and investigate ways to reduce injuries. For example, Lumber spine simulation, ACL injuries, Slip/falls.

Zabet Moghaddam, Masoudmasoud.zabet@ttu.eduTTUExperimental Sciences Building 107Research;The Center for Biotechnology and Genomics has a Master program in biotechnology in which the students will get trained in the first year in different field of biotechnology and continue their educations in the second year working on their Master projects. I mentored many students during the first and second year of the projects. Additionally, I have worked and mentored undergraduate students as well as high school students. I always enjoyed working and training students.

I use cutting-edge technology, Mass Spectrometry, to analyze proteins and small molecules (metabolites) in majority of my research projects. Some of the projects listed below:

- MALDI-TOf as a new tool for the analysis of polyamines in plants.

- Study of cotton fiber development under water-deficit stress. 

- A proteomics approach to studying the effects of an anti-cancer compound on breast tumor cells.

Being relatively new to TTU, I have not had extensive experience here, though I do have a CUR mentor right now. I was a McNair mentor at my former university, Oregon State. I directed the graduate program there and mentored more than 40 students in that role. I have chaired more than 30 graduate committees. I involved undergraduate students in my research at OSU, including publishing with them.

To be most helpful, the student should have taken a research methods course (either in HDFS, Psychology, Sociology). They should also be familiar with excel and ideally, SPSS. Our interdisciplinary project includes information that relates to many possible interests on the part of the scholar: work and family life; child development in the context of parental work demands and frequent parental absence; technology and its impacts on families; communication; daily health behaviors of adults and children; coping and stress. Because the project is multi-method and includes information from multiple family members, a scholars with interest in methodology would find fertile ground in the data also.

In my current funded project, I employ 5-8 graduate students. My lab would allow a student to see up-close how graduate students organize their work. We will be nearly done with data collection in summer 2010, so the research would be primarily reading over qualitative transcripts, compiling information for lay publications (such as newsletters), and entering quantitative data that will then be analyzed by the research team. Our lab typically presents our work at a national conference in November, so the student would observe and participate in that effort. By the end of fall, we will be focusing on data analysis, and the student would have an increasingly responsible role in such efforts.
