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.
