Vasu Tewari

I am a Hans Rademacher Instructor of Mathematics at the University of Pennsylvania. Prior to this, 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.
