Omer Tamuz is a professor of economics and mathematics at Caltech. His research lies at the intersection of microeconomic theory, probability, dynamics, and group theory. In economics, he studies decision making under uncertainty; in mathematics, he works on problems in probability, dynamics, and group theory. His recent work is often interdisciplinary, linking ideas from economics to mathematics and physics. He earned his MSc and PhD in mathematics from the Weizmann Institute (2013) and his BSc from Tel Aviv University (2006), where he was also part of an astronomy research team studying extrasolar planets and binary star systems. Before joining Caltech in 2015, he was a Schramm Postdoctoral Fellow at MIT and Microsoft Research. His honors include an NSF CAREER Award, a Sloan Research Fellowship in Mathematics, and a Division of the Humanities and Social Sciences Brass Teaching Award. He currently serves as chair of Caltech's undergraduate admissions committee.
