Short biography:

Professor Ercegovac earned his PhD ('75) and MS ('72) in computer science from the University of Illinois, Urbana-Champaign, and BS in electrical engineering ('65) from the University of Belgrade, Serbia. He retired in 2020 after 45 years on the faculty at UCLA. He has specialized in research and teaching in digital arithmetic, digital design, and computer system architecture. His continuing research is in the areas of left-to-right and online  arithmetic algorithms, approximate arithmetic, composite algorithms,  design for low,  power and arithmetic in application-specific architectures. His research contributions have been extensively published in journals and conference proceedings. He is a coauthor of two textbooks on digital design and of a monograph and a book in the area of digital arithmetic. Dr. Ercegovac has been involved in organizing the IEEE Symposia on Computer Arithmetic since 1978. He served as an associate editor of the IEEE Transactions on Computers and as a subject area editor for the Journal of Parallel and Distributed Computing. He received a Medal of Ecole Normale Superieure de Lyon, France, in 2015, a Distinguished Alumni Educator Award in 2013 from the Department of Computer Science, University of Illinois Urbana-Champaign, and Lockheed-Martin Corporation Excellence in Teaching Award in 2009. Dr. Ercegovac is a foreign member of the Serbian Academy of Sciences and Arts, Fellow of the IEEE, and a member of the ACM. Curriculum Vitae [CV.pdf]
