I am currently a postdoc at Washington University in St. Louis studying no-slip billiards with Renato Feres. For the spring 2017 semester I am teaching
Math 131 Calculus I
and Math 370 Combinatorics

(Left) The projection of a sampling of orbits in the velocity phase spacefor a regular no-slip pentagonal billiard. The families of concentric circles show the structure around elliptic periodic points, with some small, intricate families entered around high order periodic points.

(Right) The projection for a regular hexagon table, with orbits identified by color grading so that orbits with similar initial conditions are similarly colored.
