Adrian received his Ph.D. in mechanical engineering from the University of Toledo, OH, and his B.S. and M.S. in aerospace engineering from Polytechnic University of Bucharest, Romania. Before joining the Department of Aerospace Engineering @ MSU in August 2012, he was a postdoctoral fellow at Johns Hopkins University, MD, in the research group of Professor Charles Meneveau. Since he became a faculty member of the Department of Aerospace Engineering @ MSU, he has been in a couple of other places as fellow or visiting scholar, such as three summers at Air Force Research Lab, and one summer at the Center for Turbulence Research Summer Program, Stanford University. He is currently the director of undergraduate studies in the Department of Aerospace Engineering.
