Keith Marzullo's research interests and expertise include fault-tolerant computing with focus on the Internet, Grid computing, and other distributed networks. These kinds of systems have radically changed the challenges of assuring reliability. He is currently working on failure models for wide area systems, and devising optimal protocols for systems in which failures are not independent and identically distributed. His research is supported by NSF. Dr. Marzullo joined the UCSD Jacobs School faculty in 1993 and is now the department chair. Before coming to UCSD, he was an associate professor at Cornell University and vice president at ISIS Distributed Systems, Inc., in Ithaca, New York. He received a Ph.D. from Stanford University in electrical engineering in 1984.
