Behrooz Parhami

Behrooz Parhami is a Distinguished Professor in the Department of Electrical and Computer Engineering at the University of California, Santa Barbara, where he has been a faculty member since 1988. He previously served as Associate Dean for Academic Personnel in the College of Engineering from 2009-2012 and as Vice Chairman of the ECE Department from 1990-1992. Before joining UCSB, he was a professor at Sharif University of Technology in Tehran, Iran from 1974-1988. He received his PhD in Computer Science from UCLA in 1973.

Professor Parhami's research focuses on computer arithmetic, parallel processing, and fault-tolerant computing. In computer arithmetic, he pioneered generalized signed-digit number systems as a unified framework for redundant representations. His work in parallel processing includes contributions to database processors, interconnection networks, and scalable architectures. In fault tolerance, he developed systematic data-driven methodologies for reliable hardware and software systems. He has also made significant contributions to adapting computer technology for Persian language computing.

His scholarly output demonstrates consistent focus on fundamental computing principles. Recent publications show continued exploration of unconventional number systems, reliability analysis, and specialized computing architectures. His work bridges traditional computer architecture with emerging technologies including atomic-scale computing, neuromorphic systems, and novel memory technologies. His research maintains relevance through connections to both theoretical foundations and practical implementations.
