Research
My research is in combinatorial probability. Recently, I have been thinking about two interacting particle systems, the stochastic sandpile and the parking process, and combinatorics for shifts of finite type.

Bridge articles
Bridge conventions and bidding. An introduction to the basics of bridge I wrote to teach friends and family about the game. Contains an explicit bidding tree for SAYC.
Bridge articles. Some short, fun articles I wrote to teach advanced bridge situations, e.g. squeezes and coups.
