I am a Lecturer on the faculty of Bar-Ilan University.

Several years ago I was a Post-Doctoral Fellow in the Department of Statistics and Operations Research at Tel-Aviv University working with Prof. Ehud Lehrer and Prof. Eilon Solan.

I completed a PhD  at the Einstein Institute of Mathematics (with affiliation with  the Centre for the Study of Rationality) at the Hebrew University of Jerusalem, with a thesis on game theory. My PhD supervisors were Prof. Dov Samet and Prof. Sergiu Hart.

Prior to that I earned a B.A. in Mathematics at Princeton University and an M.A. in Mathematics at UCSD.
My Erdős number is 3.

My research is focussed on game theory and my current research interests include Bayesian games, incomplete information, beliefs and knowledge, epistemic game theory, and no trade theorems. I have also researched topics in risk measurement, coalitional games and the theory of evolution.
