Vinayak M. Kumar

Hello! I am a fourth-year Ph.D. student in UT Austin's Computer Science Theory group, fortunate to be advised by David Zuckerman. I am interested in combinatorial and probabilistic problems in pseudorandomenss, like hashing, coding theory, and circuit lower bounds.

Before joining UT Austin in 2021, I received my B.S. in mathematics and computer science at Caltech. I'm extremely grateful to have been mentored by Venkatesan Guruswami and Leonard Schulman during my undergraduate years.
