BIOSKETCH

Harry Wechsler received the Ph.D. in Computer Science from the University of California, Irvine, in 1975.  From 1976 to 1978 he was  Assistant Professor and System Manager for the Advanced Automation Research Laboratory (AARL) in the Department of Electrical Engineering at Purdue University, during 1978-1980 he was  Assistant Professor at the University of Wisconsin, and in 1980 he became  Associate Professor of Electrical Engineering at the University of Minnesota.  Since 1987 he has been  Professor of Computer Science at George Mason University (GMU).  Dr. Wechsler is the Director for the Distributed and Intelligent Computation Center at GMU http://cs.gmu.edu/~wechsler/DIC_Center/ since 1995. His academic career includes visiting Professorships at Institut National de Recherche en Informatique et en Automatique (INRIA) (France), Kyoto University (Japan), Technion (Israel), the Center for Automation Research at The University of Maryland, Centre National de Recherche Scientifique (CNRS) and University of Paris-Orsay  (France), Commonwealth of Science and Industry Research Organization (CSIRO) (Australia), University of Geneve (Switzerland), Russian Academy of Science (Moscow), and the Chinese Academy of Sciences (Beijing).
