Biography

Dr. Tsiotras joined the faculty of the School of Aerospace Engineering at the Georgia Institute of Technology in 1998 as an Associate Professor. Prior to joining the faculty at Georgia Tech, Dr. Tsiotras was an Assistant Professor of Mechanical and Aerospace Engineering at the University of Virginia. From 1993 to 1994 he was a Post-doctoral Fellow at Purdue University and during 1989 he was affiliated with the Interdisciplinary Center of Applied Mathematics at Virginia Tech, where he worked on trajectory optimization for aerospace vehicles. He has also held visiting appointments with  INRIA, Rocquencourt, the Laboratoire d’ Automatique de Grenoble, and the Ecole des Mines de Paris in  France. He has published over 150 journal and conference papers in the area of dynamics and control of mechanical and aerospace systems. His current research interests include analysis and control of spacecraft, real-time optimal control, and control of autonomous and semi-autonomous vehicles. Dr. Tsiotras is a recipient of the NSF CAREER award, the Sigma Xi President and Visitor’s Award for Excellence in Research as well as numerous fellowships and scholarships. He is an Associate Editor for the IEEE Control Systems Magazine, and a past Associate Editor of the AIAA Journal of Guidance, Control, and Dynamics and of Dynamics and Control. He is an Associate Fellow of the AIAA, and a Senior Member of the IEEE.
