CRESSE Researchers

Richard WilkinsDr. Richard Wilkins holds a Ph.D. (1991) in physics from the University of Michigan. His research interests focus on radiation effects and dosimetry, and he has co-authored over fifty journal publications on subjects from single-electron tunneling to radiation biology. In collaboration with Rice University, he led an effort to perform the first radiation experiments on carbon nanotube materials for which he was awarded a Group Achievement Award from NASA in 2001. He is currently an Associate Professor in Electrical and Computer Engineering and director of the Center for Applied Radiation Research (CARR) since 2000. Dr. Wilkins’ research interests are in radiation effects on electronic materials and devices, nano-scale materials and devices and shielding/structural materials, radiation dosimetry instrumentation and measurements.  More on Dr. Wilkins

Brad GerseyDr. Brad “Buddy” Gersey holds a Ph.D. in radiation physics from the Department of Radiological Health Sciences at Colorado State University. His graduate research was funded under the NASA Specialized Center of Research and Training (NSCORT) grant which was jointly awarded to Colorado State University and the Berkeley National Laboratory. His research specialty is in the field of radiation dosimetry called microdosimetry, the study of and measurement of energy deposition by radiation in very small volumes of material on the order of several micro-meters across. Microdosimetry has scientific and engineering applications in radiation effects on electronics, radiation carcinogenesis, radiation oncology, and radiation damage of materials. His research interests include the application of microdosimetry to radiation effects on human tissue and cellular structures, electronics components and systems, and composite multifunctional materials. He also focuses on the development of next generation space radiation detection systems. Gersey is currently a Research Scientist Group Leader for the Center for Radiation Engineering and Science for Space Exploration (CRESSE) at Prairie View A&M University.  More Dr. Gersey
