I am a postdoctoral researcher at the Department of Computer Science of University of Haifa, working with Professor Noga Ron-Zewi. Previously, I was a postdoc at IIT Kanpur working with Professor Nitin Saxena. I completed my Ph.D. in computer science at Caltech in 2017, under Professor Chris Umans.

My research interests include algebraic methods in theoretical computer science, pseudorandomness and its connections with coding theory, algorithms in number theory and algebra.

Research
