AREAS OF INTEREST

Dr. Rennels received the B.S.E.E. degree from Rose Hulman Institute of Technology in 1964, the M.S.E.E. from Caltech in 1965, and the Ph.D. in Computer Science from UCLA in 1973. He is principal investigator of research projects in fault-tolerant computing sponsored by the Aerospace Corporation, NSF, ONR, Hughes Aircraft, and TRW. He has also been responsible for the design and experimental validation of several fault-tolerant computers at the Jet Propulsion Laboratory. Dr. Rennels was the general chairman of the 12th International Symposium on Fault-Tolerant Computing in 1982. He is a member of the IFIP Working Group 10.4 on Reliable Computing and Fault-Tolerance, and was chairman of the IEEE Computer Society Technical Committee on Fault-Tolerant Computing in 1988 and 1989. His research interests are computer architecture and fault tolerant computing.

Professor Rennels is currently the Vice-Chair of Undergraduate Affairs for the Computer Science Department.
