About

I am currently a Postdoc hosted by Dr. Ittay Eyal at Technion and Dr. Fan Zhang at Yale.

I received Ph.D. and M.S. in Computer Science from Purdue University, advised by Dr. Aniket Kate. I studied financial engineering as an undergraduate.

My current research interests are in secure distributed computations.
