About

Dr. James W. Gregory is an associate professor in the Department of Mechanical and Aerospace Engineering, and Associate Director for UAS of the Aerospace Research Center at The Ohio State University. He received his doctorate and masters degrees in Aeronautics and Astronautics from Purdue University in 2005 and 2002, respectively. He received his Bachelor of Aerospace Engineering from Georgia Tech in 1999, graduating with highest honors. Dr. Gregory’s research interests lie in the field of unsteady, separated wakes – with specific interests in rotorcraft aeromechanics, bluff body wake control, and development of advanced measurement techniques. His work focuses on understanding and controlling compressible dynamic stall of rotorcraft blades; flow control of wakes, targeting three-dimensional wake structures and their instabilities; and development of fast-response pressure-sensitive paint as a diagnostic for unsteady flows. He is also active in UAS research, including flight testing of vehicle performance and systems integration studies. He serves as PI for Ohio State as a core member of the ASSURE FAA Center of Excellence on Integrating UAS in the NAS. Funding for his work includes grants from ARO (Young Investigator Award), ARL, AFOSR, AFRL, FAA, NASA, Sikorsky, and Honda R&D. His research has resulted in the Thomas Hawksley Gold Medal, a best paper award presented by the Institution of Mechanical Engineers; and the Alfred Gessow Award for co-author of the Best Paper at the 68th American Helicopter Society Forum. Dr. Gregory’s teaching innovations have led to the McCarthy Engineering Teaching Award, the Department of Aerospace Engineering Outstanding Professor Award, and the SAE Ralph Teetor Award. His work experience includes stints at the US Air Force Research Laboratory Air Vehicles Directorate, Delta Air Lines, NASA Glenn Research Center, Tohoku University in Japan, and as a Fulbright Scholar at the Technion in Israel. He has also served as a policy fellow at the National Academy of Engineering through the Christine Mirzayan Science & Technology Policy Fellowship. Before arriving at Ohio State, he completed a postdoctoral fellowship at the U.S. Air Force Academy, funded through the National Research Council Research Associateship Program. He holds a private pilot license for single-engine land-based aircraft.
