About

Professor of Mathematics at the University of Michigan. My research interests are in combinatorial algebraic geometry, particularly Schubert calculus, matroids and cluster algebras. I also enjoy thinking about number theory and computational mathematics.

Disclaimer: I have >= 15 years of answers on MO. I will often not respond to comments on old answers. Sorry, there is a point where I need to limit how much time I put in.
