About Me
I'm a postdoc in the group of Umesh Vazirani at UC Berkeley. I finished my PhD in 2016 at MIT, advised by Dana Moshkovitz. There I was a Simons Graduate Fellow in Theoretical Computer Science (20152016) and a recipient of a NSF Graduate Fellowship. I obtained my B.A. in Mathematics from the University of Southern California in 2010.
News: I will be joining the University of Toronto as an Assistant Professor of Computer Science and Mathematics in Summer 2018!email: hyuen@cs.berkeley.edu
