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 10 years of answers on MO. I do not feel obliged to respond to every comment I get.
