- Professor Emeritus
Dr. Melhem has received the following degrees: BS (Electrical Engineering, 1976) from Cairo University; BS (Mathematics, 1978) from Ein-Shams University, Cairo; MA (Mathematics, 1981), MS (Computer Science, 1981), and PhD (Computer Science, 1983) from the University of Pittsburgh.
He was Assistant Professor in the Department of Computer Science at Purdue University 1984-87 (on leave 1985-87), and Visiting Professor in the Department of Mathematics at the University of Pittsburgh 1985-86.
Since 1986 he has been on the faculty of the Department of Computer Science at the University of Pittsburgh. He has published numerous papers in the areas of systolic architectures, parallel computing, fault-tolerant computing, and optical interconnection networks. He served on program committees for several conferences and is on the Editorial Board of IEEE Transactions on Computers. He is a member of the IEEE Computer Society, the Association for Computing Machinery, and the International Society for Optical Engineering.
His research interests include: parallel and distributed high-performance computing, fault-tolerant computing, multiprocessor interconnection networks, real-time systems and optical computing.
