I am a faculty member (senior lecturer, aka, assistant professor) at the Department of Computer Science, and a member of Applied Cryptography and Cyber Security Research Center.

Between 2019 and 2022, I was a postdoc in the Department of Computer Science at the Technion, hosted by Prof. Yuval Yishai
I completed my Ph.D. in 2019 working in the Applied Cryptography and Cyber Security Research Center at Bar-Ilan University, under the supervision of Prof. Yehuda Lindell.
I received my M.Sc. from the Department of Computer Science, Bar-Ilan University, under the supervision of Prof. Yehuda Lindell.

My research interests are in cryptography, with a focus on secure multiparty computation.
