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 Bachelor of Aerospace Engineering from Georgia Tech, and masters and doctorate degrees in Aeronautics and Astronautics from Purdue University. His research interests focus on development of pressure-sensitive paint as an advanced measurement technique, drag reduction of bluff body wakes via aerodynamic flow control, and flight testing of unmanned aircraft systems. His work experience includes stints at the US Air Force Research Laboratory Air Vehicles Directorate, the US Air Force Academy, Delta Air Lines, NASA Glenn Research Center, Tohoku University in Japan, and as a Fulbright Scholar at the Technion in Israel. He is an instrument-rated private pilot. Tianshu Liu is a professor and the director of Applied Aerodynamics Laboratory at Western Michigan University. He received a Ph.D. in aeronautics and astronautics from Purdue University in 1996. He was a research scientist at NASA Langley Research Center in 1999-2004. His research areas are experimental and applied aerodynamics and fluid mechanics. In particular, he has contributed to image-based measurement techniques for various physical quantities such as surface pressure, temperature/heat-transfer, skin friction, velocity fields, aeroelastic deformation, and distributed and integrated forces. His topics also include videogrammetry and vision for aerospace applications, flow control, flapping flight, flight vehicle design, turbulence and transition, and flight tests.
