I am broadly interested in theoretical computer science and I am part of the theory group at Cornell University. Before this I was a postdoctoral researcher at the Institute for Advanced Study, Princeton with Avi Wigderson, a Microsoft Research Fellow at the Simons Institute, Berkeley, and a graduate student at UT Austin under David Zuckerman. Some press coverage of my research: BBC, Science News, and Communications of ACM. Invited survey article: A Recipe for Constructing Two-Source Extractors ACM SIGACT News Complexity Theory Column , June 2020 issue General audience article: How random is your randomness, and why does it matter? with David Zuckerman.CV.
I co-organize the Cornell CS theory seminar. Drop me a line if you are interested in giving a talk!
