Zhongkui Hong Receives NSF Support for Cellular Mechanical Oscillations Research
Dr. Zhongkui Hong is an Associate Professor in the department. His research is focused on biomechanics in cardiovascular diseases, and mechanics in biomaterial design and tissue engineering. In his most recent project, funded by the NSF, he and his team study knowledge gaps in cellular mechanical oscillations and propose an innovative approach that seeks to advance efforts to treat and prevent cell migration-relevant diseases such as cardiovascular diseases and cancers. Periodic oscillations exist broadly in animal cell mechanics. These mechanical oscillations of cells are thought to contribute to disease development, such as cardiovascular disease and cancer by triggering cell migration, moving from one location of the body to another.
To elucidate the molecular mechanism of cellular mechanical oscillations and their functions in cell migration, Dr. Hong's team is employing an innovative approach integrating a series of novel experimental approaches and data-driven mathematical models to monitor cellular mechanical oscillations, cytoskeleton dynamics, as well as cell membrane undulation and polarization.
Alexander Idesman Receives Research Award
Dr. Alexander Idesman, a Professor in the department, recently received the Whitacre Engineering Research Award. Dr. Idesman's research focuses primarily on computational mechanics related to the modeling of heat transfer, acoustic and elastic wave propagation, and stresses in structural components under static and dynamic loadings. Recently, he has developed a new general numerical method for the solution of partial differential equations used for the description of the abovementioned problems. The new approach, called the Optimal Local Truncation Error Method (OLTEM), significantly reduces the computation time by a factor of 1000 or higher as compared to existing numerical approaches such as the finite element method, the finite volume method, and the finite difference method.
Another advantage of OLTEM is the use of unfitted Cartesian meshes for complex irregular
domains and interfaces without the need for complicated mesh
generators. Due to these advantages, many important engineering problems that cannot be currently solved due to prohibitively large computation time can be
analyzed by OLTEM.
NASA-funded University Student Research Challenge
Texas Tech University is taking part in the NASA- funded University Student Research Challenge to find ways to make vectored-thrust, ducted-fan, electric vertical-takeoff-and-landing (eVTOL) vehicles more efficient and less noisy. Led by Dr. Victor Maldonado, the team of students will be testing a wind-tunnel model of a wing design that reduces exposure of the ducted fans in cruise flight and a fan-blade design that promises to reduce noise.
Their eVTOL concept involves 20 tilting fans mounted on four flaps under the trailing edge of a main wing with a heavily under-cambered airfoil that hides the fans in cruise flight, reducing drag. The fans are blended into the fuselage to improve aerodynamic efficiency, taking inspiration from Dr. Maldonado's previous blended wing body aircraft research. The first goal of this NASA project is to test the concept in a wind tunnel to compare it with a baseline design.

Engineering Professor Looking to Mitigate Injury Risks for Military Free-Fall Jumpers
Dr. James Yang, a professor of Mechanical Engineering, recently received a $450,000 grant from the U.S. Army Medical Research and Development Command (USAMRDC) to model the biometrics of parachute opening shock. The focus of his project is to study what happens inside the human body during parachute opening shocks.
His goal is to develop a multiscale human model to conduct biomechanical analyses
where they can study the parachutists' potential injuries during this action, seeking
the improvement of capabilities and safety of these operations. The results will be
used by instructors and developers to prevent, reduce, screen, and diagnose musculoskeletal
injuries in military free-fall parachute jumps. His research is designed to lower
injury rates in paratrooper´s bodies, but this is not the only project in mind. “Later
we'll do other aspects,” Yang said. “ The DOD is interested in what happens from the
time soldiers jump out to the landing, so this is just the first project we will be
working on.” Yang's research is part of a larger effort by the U.S. Army Aeromedical
Research Laboratory (USAARL) and the U.S. Army Research Institute of Environmental
Medicine (USARIEM) entitled “Parachute Health Hazard Effects.” “Our soldiers are our
most important asset,” said Song-Charng Kong, chair of the Department of Mechanical
Engineering. “Dr. Yang's research will mitigate the health risks in parachuting and
provide additional protection to our soldiers. The health benefits to the soldiers
go far beyond their military careers. The impact of Dr. Yang's work is tremendous.”
Stephen Ekwaro-Osire received a five-year grant to help increase the capabilities of the undergraduate engineering program at Jimma University in Ethiopia.
Dr. Stephen Ekwaro-Osire, a professor of mechanical engineering, received a five-year, $816,392 grant from Jimma University in Ethiopia to help lead the institution's Pathway Toward Global Engineers program. “This grant was motivated by the pandemic disruptions, and there are two objectives,” Ekwaro-Osire said. “One is to increase the capabilities and quality of the undergraduate engineering students from Jimma University. The second is to increase the capacity – meaning the faculty, the facilities, everything – to offer high-quality engineering programs.” Ekwaro-Osire will work with professors and administrators at Jimma University as well as local industry members and stakeholders during this process. “We aren't going to be physically teaching classes,” Ekwaro-Osire said, “but we will conduct workshops for faculty and administrators on how to do certain things and, with other additional interventions and collaborations, a shift in the educational paradigm will be facilitated.” Jimma University´s purpose is to have a program that is shock responsive. With 12,000 students, 13 engineering bachelor´s degree programs, and 1,000 undergraduate engineers a year, this is a challenge that they are excited about. Lloyd Heinze, a professor in the Bob L. Herd Department of Petroleum Engineering, also is involved and sees the opportunity for Texas Tech to recruit potential graduate student candidates for our college.
