Mootaz Elnozahy

Professor, Computer Science 
Dean, Computer, Electrical and Mathematical Science and Engineering 
Computer, Electrical and Mathematical Science and Engineering Division


Education Profile

  • ​​​​Ph.D., Computer Science, Rice University, 1993
  • M.S., Computer Science, Rice University, 1990
  • M.S., Computer Engineering, Cairo University, Egypt, 1987
  • B.S., Electrical Engineering, Cairo University, Egypt, 1984​

Research Interests

Elnozahy's research area is in systems, including high performance computing, power-aware computing, fault tolerance, operating systems, system architecture, and distributed systems. His work on rollback-recovery is now a standard component of graduate courses in fault-tolerant computing, and he has made seminal contributions in checkpoint/restart, and in general on the complex hardware-software interactions in resilience.
