About Me

I am an instructor and NSF postdoctoral fellow in the department of mathematics at MIT. I spent Spring 2014 at UC Davis as a UC President's Postdoctoral Fellow.

I received my Ph.D. in mathematics in 2012 from Caltech, under the supervision of Eric Rains. My thesis received the Scott Russell Johnson dissertation award. I completed my undergraduate degree at Stanford in 2007. I received a Firestone medal for my undergraduate honors thesis, which was supervised by Persi Diaconis and Nat Thiem.

My research interests lie in the intersection of combinatorics and representation theory.
