Dr. Liebst received his Ph.D. from the Massachusetts Institute of Technology (Aeronautical Engineering) in 1981. He is currently Professor and Head of the Department of Aeronautics and Astronautics at the Air Force Institute of Technology. Prior to arriving at AFIT in 1989, Professor Liebst was 2 years with Contraves-Goerz Corporation as a Principal Engineer and was Assistant Professor of Aerospace Engineering for 6 years at the University of Minnesota where he was voted the 1987 Best Institute of Technology Professor. Dr. Liebst’s research interests include eigenstructure assignment control, stability and control of aerospace vehicles, aircraft handling qualities, and passive and active control of large flexible structures.
