I am a professor of **economics**
and **mathematics** at Caltech. I am interested in **probability**,
**dynamics** and **group theory**, and in their applications
to topics in **microeconomic theory**,
including **information**, **risk** and **uncertainty**. I am a member of the
Caltech SISL
and DOLCIT
interdisciplinary research groups.

I got my B.Sc. in **computer science** and **physics**
from Tel Aviv University, where I participated in the
search for **extrasolar planets** with the
brilliant Tsevi
Mazeh.
In 2013 I received my Ph.D. in **mathematics** from the Weizmann
Institute, advised
by Elchanan
Mossel. From 2013 until 2015 I was a Schramm postdoctoral
fellow at the MIT math department / Microsoft
Research, where I previously was an intern of
Adam Kalai. I have been at Caltech since 2015.

Write to my gmail (omertamuz), or visit me in
Baxter Hall, room
213.

Past workshops that we have hosted at Caltech include WISE 2016, WISE 2018 and NEGT 2018.

In January 2019 I gave a public lecture at Caltech: The Long Run Behavior of Random Walks
