Teaching
I am currently not teaching for Fall 2016; see you back in the Spring!
Research Interests
I am part of the Combinatorics Group of the department. I spend my time thinking about combinatorial phenomena that have generalizations in the world of reflection groups; what is usually called, Coxeter Combinatorics. I am therefore lucky, to work with objects that though easy to grasp, reveal deep connections between algebraic, topological and geometric concepts.
Student Combinatorics Seminar
This year, Sunita Chepuri and Eric Stucky are running the Student Combinatorics Seminar.

Some things I wrote
 Parking Space Conjectures
This was my oral exam paper (no pun intended). It sets up background from Armstrong,Rhoades,Reiner's Parking Spaces paper and gives a geometric rephrasing  due to Gordon and Ripoll of their main conjecture. Be warned; nothing original made it here, but the presentation might still be useful to some.
 LyashkoLooijenga morphisms and primitive factorizations of a Coxeter element.
These are slides of a talk I gave at the Algebraic Combinatorics and Group Actions conference at Herstmonceux, UK in July 2016. We extend work of Ripoll and Bessis and consider a variant of the LLmorphism. By understanding the size of its generic fibers, one can enumerate classes of factorizations. In other words, and as far as enumerating questions go, Geometry strikes back!
A sligthly longer version including more background (and some pretty pictures) from a talk at the Minnesota Combinatorics Seminar is also available.
