I am a professor of **economics**
and **mathematics** at Caltech. My research is
in **microeconomic theory**, including **game theory**,
**learning** and **information**, as well as in **probability**,
**ergodic theory** and **group theory**. I'm also interested
in **machine learning** and **statistics**. 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.

We hosted the **Workshop on Information and Social Economics** (WISE) in 2016 and 2018.

Last winter we held the The Southern California Symposium on Network Economics and Game Theory (NEGT) here at Caltech.

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