I am a postdoctoral researcher at Cornell Tech, hosted by Prof. Rafael Pass and Prof. Elaine Shi.

I completed my Ph.D at the Weizmann Institute of Science, where I was fortunate to have Prof. Moni Naor as my advisor. I received my M.Sc also at the Weizmann Institute under the guidance of Prof. Ran Raz.

I am interested in foundations of theoretical computer science, with an emphasis on cryptography and its interplay with complexity theory.
