About me

My research mainly concerns symplectic/contact topology and Hamiltonian dynamics. I'm especially interested in applications of Floer-type theories and pseudoholomorphic curves to dynamical questions.

I did my postdoc at the Institute for Advanced Study, Princeton. My host was Prof. Helmut Hofer.

I did my Ph.D. at Tel Aviv university, under the supervision of Prof. Lev Buhovski and Prof. Leonid Polterovich.

I completed my master's degree at Weizmann Institute. My advisor was Prof. Sergei Yakovenko.

My CV can be found Here.

Teaching

In the fall semester of 2025-2026 I am teaching Differential Geometry, materials are available at Weizmann's moodle system. Before that I taught an introduction to symplectic geometry course (spring 2025).
