Vasu Tewari

I am an Assistant Professor (TT) at the Department of Mathematics at the University of Hawaii. From July 2018-December 2020, I was a Hans Rademacher Instructor of Mathematics at the University of Pennsylvania. I was on leave at the Mittag-Leffler Institute from January 2020-March 2020. From September 2015-June 2018, I was an Acting Assistant Professor at the University of Washington where my mentor was Sara Billey. I received my PhD in Mathematics in August 2015 from the University of British Columbia where I was advised by Steph van Willigenburg. I study algebraic combinatorics.
