The interplay between energy and water provides ample avenues for research. Indeed, the production of freshwater requires energy, while the production of energy requires water. My research interests in what has been called the water-energy nexus include water resources management, water resources economics, and the emerging integration of renewable energies with reverse osmosis desalination.
The overall objective of my research is to evaluate processes contributing to the absence of chlorate ClO3− on Mars by evaluating two Earth-Martian analogues. I will be studying the isotopic composition of chlorate to understand potential chlorate sources and the impact that abiotic and biotic processes have on chlorate and its isotopic signature. I am also evaluating the use of chlorate as an alternative solution to remediation of the salt marshes by introducing the concept that would be to provide chlorate as both an alternate electron acceptor, as well as atomic oxygen source, allowing for remediation of the Louisianan salt marshes impacted by the BP Horizon oil spill.
Natural perchlorate (ClO4−) in the environment is unique in that it does not all exhibit similar isotopic compositions. Natural ClO4− isotope variation is not entirely understood, but may be due to distinct production mechanisms and/or reactatants or post depositional fractionation and exchange processes capable of altering ClO4− isotope composition. My research focuses on plant uptake of ClO4− and ClO4− formation pathways involving ozone and ultraviolet radiation and whether these processes can impact ClO4− isotope composition and account for some of that variation.
My current research is on the post depositional processing of anions in extreme environments. The focus involves chlorate (ClO3−), a species in the chlorine biogeochemical cycle, and the nature of its occurrence in Antarctica. The work may also contribute to our understanding of the Martian environment, given that Antarctica is the most similar earth analog.
George R. Herrmann, P.E., P.H., C.F.M., S.I.T.
George R. Herrmann, P.E., P.H, CFM, SIT is a Ph.D. candidate in the civil engineering program at Texas Tech, specializing in water resources. Herrmann retired from the Texas Department of Transportation in June 2012 after 24 years with that agency. His research is centered around hydrologic techniques, sediment transport in ephemeral streams, and stream stability in ephemeral and arid land streams. He has spoken on these topics in state, national, and international conferences.
My home language name is Yue Li, yet every colleague in the department calls me Beatrice. I became a member of the Environmental Ph.D. club since Fall 2012. My research focuses on remediation of recalcitrant organic compounds and groundwater hazardous elements by metal catalyzed radical reactions. I enjoy the academic atmosphere here at Texas Tech. From here, it's possible.
My research project was to assess the potential use of some gypsum materials to manage mercury and methyl mercury production in contaminated sediments. I then moved to Lubbock for doctoral studies within the Department of Civil and Environmental Engineering. I am still working on sediment remediation with Dr. Danny Reible but also Dr. Fazle Hussain. The new project will include turbulence above the sediment-water interface.
Paula is a first year civil engineering Ph.D. student and graduate of the Master of Environmental Engineering program. Her research interests include water and wastewater treatment, focusing on non-selective advanced oxidative processes for small scale water treatment facilities. She is currently investigating the use of organoselenium and zero-valent iron compounds as a potential oxidative process. Paula’s goal is to pursue a career in either academia or industry focusing on water and wastewater treatment.
I am currently researching the uptake rate of pharmaceuticals within food crops. The scope of my thesis has been the uptake rate of three common pharmaceuticals (Prozac, Ibuprofen and an estrogen) within celery after being exposed for various time periods. I am also investigating the metabolites of the pharmaceuticals movement and occurrence within the plant structure.
My research interests are the applications of graphene nano materials to solve environmental pollution problems. Graphene a two dimensional nano material is the world’s thinnest and strongest material, this material is a conductor of heat and electricity. My work so far has involved working with this material to determine its adsorption capacity of carbon dioxide. I would like to continue working this material to determine the mechanisms controlling the adsorption of gases and also to find out the specificity of these materials towards environmental pollutants. To summarize my interest, “I would like to understand the application and implications of the use of these materials in environmental engineering.”
