Ran Raz is a professor of theoretical computer science at the Weizmann Institute of Science, Israel. Currently, he is also a five-year visiting professor at the Institute for Advanced Study, Princeton. Ran received his B.Sc. in mathematics and physics (1987) and Ph.D. in mathematics (1992) from Hebrew University of Jerusalem. After spending two years as a postdoc at Princeton University, he joined the Weizmann Institute of Science in 1994. Ran was a visiting professor at the Institute for Advanced Study (2000–2001, 2002) and a visiting professor at Microsoft Research Redmond (2006) and Microsoft Research New England (2009).
Raz’s main research area is complexity theory, with a focus on proving lower bounds for computational models. More specifically, he is interested in Boolean and arithmetic circuit complexity, communication complexity, probabilistically checkable proofs, quantum computation and communication, and randomness and derandomization.
