Dr. Mark Gragston received his Ph.D. in Mechanical Engineering from The University of Tennessee-Knoxville in 2018. His primary research focus is the development and application of laser and optical based techniques for examining high-speed fluid phenomena including the dynamics of boundary layers, shock-boundary layer interactions, and more. Techniques utilized include PLIF, Radar REMPI, schlieren, FLDI, and others. Mark also has an interest in applying advanced image processing techniques to extract quantitative information from high-speed images and the development of novel imaging techniques. Furthermore, he is developing a high-enthalpy wind tunnel to study heat transfer and real gas effects in hypersonic flows. He is a member of the American Institute of Aeronautics and Astronautics, the American Physical Society, the National Society of Black Engineers, and the Optical Society. He was a 2020 AFOSR Summer Faculty Fellow and has two U.S. patents related to optical measurements and imaging.
