Professor Huynh received the M.S. and Ph.D. degrees in Computer Science from the University of Saarland (Germany) in 1977 and 1978, respectively, where he remained as a postdoctoral research associate until 1982. From 1982 to 1983 he was a Visiting Assistant Professor at the University of Chicago. He then spent three years as an Assistant Professor of Computer Science at Iowa State University before joining the Computer Science faculty at the University of Texas at Dallas as an Associate Professor in 1986. Dr. Huynh was promoted to Full Professor in 1991.  From 1997 through 2009 he served as Head of the Computer Science Department, which grew significantly during his tenure and has been one of the top five computer science degree producers in the nation in the last several years. Professor Huynh is currently an Associate Dean in the Erik Jonsson School of Engineering and Computer Science. He has been a member of the Advisory Board of the Journal of Automata, Languages and Combinatorics since 1996.
