I am a senior lecturer at the Einstein Institute of Mathematics at the Hebrew University of Jerusalem, Jerusalem, Israel.

Before that: I was a Postdoctoral Fellow at the University of British Columbia, Vancouver, B.C., Canada.

Before that: I was a Member at the Institute for Advanced Study, Princeton, New Jersey.

Before that: I received my PhD from Tel-Aviv University, under the supervision of Prof. Micha Sharir.
