Keith Marzullo is currently Director of the CISE Division of Computer and Network Systems at the National Science Foundation, and the Chair of the Computer Science and Engineering Department at the University of California, San Diego. He has been on the UCSD faculty since 1993.
Marzullo received his PhD in Electrical Engineering from Stanford University in 1984; for his PhD he developed the Xerox Research Internet Clock Synchronization protocol, which was one of the first practical fault-tolerant protocols that addressed this issue. In 1986, he left Xerox and joined the CS Department at Cornell University where with colleagues Ken Birman and Robert Cooper, he started the company ISIS Distributed Systems, which provided middleware for fault tolerant distributed applications; this software was used by financial and investment institutions. He served as a Professor at Large in the Computer Science Department at the University of Tromso from 1999-2003, and was Chair of ACM SIGOPS from 2003-2007.
Marzullo's current research focuses on issues in distributed systems and security, and on scalable protocols for data center communication fabrics.
