Assistant professor at the CSE Department at the Ohio State University.
Office: Dreese Lab 489
E-mail: pooyahat at gmail dot com
Research Interests: Pseudorandomness, Complexity Theory, Combinatorics, Analysis of Boolean Functions
I spent two years as a postdoc at UT Austin hosted by David Zuckerman. I also spent two years as a postdoc at DIMACS and at the Institute for Advanced Study. I received my PhD from the Computer Science Department of University of Chicago, where I was lucky to be supervised by Alexander Razborov and Madhur Tulsiani.
