Biographical Sketch

Dr. Andrew Ketsdever is currently an Assistant Professor in the Department of Mechanical and Aerospace Engineering at the University of Colorado at Colorado Springs. He came to UCCS from the Air Force Research Laboratory's (AFRL) Propulsion Directorate at Edwards Air Force Base in California. Dr. Ketsdever received his Ph.D. from the University of Southern California (USC) in 1995 where he is currently a Research Professor in the Department of Aerospace and Mechanical Engineering. He recently completed a Visiting Professorship in the Department of Astronautics at the United States Air Force Academy (2004-2007).


Dr. Ketsdever has worked in the areas of advanced propulsion design and testing, rarefied gas dynamics, microfluidics, micropropulsion and spacecraft-thruster interactions since starting at AFRL in 1992. He holds patents in the areas of micropropulsion and nano-ignition of propellants. Dr. Ketsdever has served on the American Institute of Aeronautics and Astronautics (AIAA) Thermophysics Technical Committee where he was the chairman of the Education Subcommittee. He has also been involved with The AIAA Working Group in Microfluidics. Dr. Ketsdever has authored or co-authored more than 90 technical papers. He also co-edited an AIAA Progress in Astronautics and Aeronautics series book entitled Micropropulsion for Small Spacecraft. Dr. Ketsdever is currently an associate editor for the Journal of Spacecraft and Rockets. For current research projects see Dr. Ketsdever's website listed below.
