## Hello World!

I am a fourth-year graduate student studying mathematics at Columbia University. My advisor is Andrei Okounkov. Very broadly, my interests lie at the intersection of algebraic geometry, representation theory, and mathematical physics. In particular I am interested in enumerative geometry. Lately I've been thinking about various Donaldson-Thomas type theories.

I graduated in June 2016 from the University of Waterloo, where I majored in Computer Science and Pure Mathematics.
