My Picture
Hi! I've just completed my Ph.D. at Weizmann Institute of Science under the advisement of Ran Raz. I'm expected to join Caltech as a CMI postdoctoral fellow in few months. I'm interested in many aspects of theoretical computer science, with focus on pseudo-randomness, and related mathematics. Please contact me for any question. My mail is my last name followed by
