I am an Assistant Professor in the Mathematics Department at George Washington University. I received my Ph.D. at MIT in 2012 under the guidance of Alex Postnikov, and worked for several years as a post-doc in the combinatorics group at the School of Mathematics, University of Minnesota, Twin Cities. My ErdÅ‘s number (see also) is at most 3.

### Research

I'm interested in combinatorics, especially enumerative and algebraic. Much of my recent work involves the combinatorics of permutations, GL_{n}(**F**_{q})-analogues, and Coxeter groups. You can find me on the arXiv or MathSciNet.

### Teaching

In Spring 2018, I am teaching Math 1231 (Calculus 1) and 3632 (Graph Theory). Students should look for all course materials on Blackboard.

### Office Hours

My office hours for Spring 2018 are M 10–12 and Tu 3–4.

### Seminar

This year I am co-organizing the GWU combinatorics seminar with Joe Bonin
