JOSEPH JÁJÁ (joseph@isr.umd.edu)

Professor of Electrical Engineering and the Institute for Systems Research

Joseph JáJá received his B.S. degree with high distinction in Mathematics from the American University of Beirut in 1974. He was awarded his M.S. and Ph.D. degrees in Applied Mathematics by Harvard University in 1976 and 1977, respectively. Dr. JáJá worked as a Teaching Assistant from 1976-77 at Harvard University. He served as an Assistant Professor of Computer Science from 1977-82 and as an Associate Professor of Computer Science from 1982-82 at the Pennsylvania State University. In 1983 he became an Associate Professor of Electrical Engineering at the University of Maryland and joined the Systems Research Center as a research faculty appointment in 1985. He was promoted to full Professor in 1987. He served as the ISR Associate Director for Research from 1988 to 1994. He has been the Director of the Institute for Advanced Computer Studies since July 1994.
