I am a PhD student in computer science at Stanford University, advised by Dan Boneh and David Mazières.

I am broadly interested in computer security, systems, and applied cryptography.

Previously, I completed my MSc in computer science in the Weizmann Institute of Science under the supervision of Robert Krauthgamer. I hold a BSc in computer science, physics and mathematics from the Hebrew University of Jerusalem, where I graduated from the Talpiot program. I also worked for a few years as a software engineer and a team leader in government and industry, focusing on cyber security, identity management, and data analytics.
