I am a lecturer in the mathematics department at Ohio
State University. I was a postdoc at University of Connecticut
last year, an NSF postdoc at University of Minnesota
from 2013 to 2016 and a postdoc during the 2012-2013 year at MSRI and UC Berkeley. I completed my
PhD in 2012 at
University of Michigan under the supervision of Sergey Fomin.
In Fall 2017 I am teaching Math 2173: Engineering Mathematics B.
My interests lie in the field of algebraic combinatorics, and more
specifically, cluster algebras. I would like to better understand
how cluster algebras relate to projective geometry and discrete

I play bridge in my free time. An article about my team back in
Michigan was written here (thanks to
Jin for supplying the file).
