One-Page Technical Biography

Behrooz Parhami received his BS degree from Tehran University and MS degree from Oregon State University, both in electrical engineering, in 1968 and 1970, respectively. He served as Acting Assistant Professor at University of California, Los Angeles, for 1.5 years after obtaining his PhD degree in computer science from that institution in 1973. From 1974 to 1988, Professor Parhami was with Sharif (formerly Arya-Mehr) University of Technology in Tehran, Iran, where he carried out research in various aspects of computer architecture and was also instrumental in national projects in technology transfer, educational planning, curriculum development, and standardization. He was the principal founder of the Informatics Society of Iran and served as its first President and Editor-in-Chief for 5 years, while at the same time guiding the IEEE Iran Section through a turbulent decade. He made numerous contributions to adapting computer technology to the needs of Persian-language computing and user interfaces and is recognized as a pioneer in this area.

Following one-year visiting (sabbatical leave) appointments at the University of Waterloo and Carleton University in Canada, Professor Parhami joined University of California, Santa Barbara, in 1988, where his areas of teaching and research include computer arithmetic, parallel architectures and algorithms, and dependable (fault-tolerant) computing. He has made important contributions in each of these fields. In the early to mid 1970s, he played a key role in the initiation of an area of R&D that came to be known as “database processors.” His current work in parallel processing is focused on VLSI-based and highly parallel architectures, particularly their interconnection networks. In computer arithmetic, he pioneered the discussion of generalized signed-digit number systems and the associated high-performance arithmetic algorithms as a unified framework for dealing with redundant representations and finding optimal designs with a wide range of technologies including binary, multi-valued, and optical logic implementations. In dependable or fault-tolerant computing, he has dealt with the synthesis of reliable hardware and software systems through a unified data-driven methodology and associated voting schemes.

Professor Parhami has published textbooks on parallel processing (Plenum, 1999), computer arithmetic (Oxford, 2000), and computer architecture (Oxford, 2005), along with over 220 technical papers in peer-reviewed journals and international conferences. He is a Fellow of IEEE, a Chartered Fellow of the British Computer Society, a member of ACM, and a Distinguished Member of the Informatics Society of Iran. He serves on the editorial boards of IEEE Trans. Parallel and Distributed Systems and International J. Parallel, Emergent and Distributed Systems. He received the IEEE Centennial Medal in 1984. His consulting activities revolve around the design and evaluation of high-performance digital systems, including intellectual property considerations and use of massive parallelism.
