About me

I have a PhD in math from Harvard University, where my advisor was Dennis Gaitsgory. My thesis was on the geometric Langlands program, and in particular "quantum Langlands", a somewhat conjectural generalization. I have a soft spot for algebraic groups and representation theory in general, and I also had a good time teaching a tutorial (special-topics course) on tropical geometry in the fall of 2008. Evidence of my enjoyment of teaching and writing can be found in the expository materials scattered around this site.

I am an RTG postdoc in the algebraic geometry group at the University of Michigan. Last year I was a lecturer at UCLA.
