My research is in combinatorial probability. Recently, I have been thinking about interacting particle systems, and geometric probability (coverage processes).


  • A smooth transition from Wishart to GOE. JOTP, 2018.
  • Activated random walk on a cycle (preprint)
  • Other mathematical writings

    Collisions among random walks. A short paper I wrote about collisions of random walks. Has some original results about collisions among 2 and 3 random walks on the line and on a cycle, and short surveys of some papers on the subject.

    Intersections of random sets. An ongoing project on intersections of random sets on the real line, and random disks in the plane.

    Undergraduate honors thesis. An investigation of percolation on finite boxes in Z^2.

    Bridge articles

    Bridge conventions and bidding. An introduction to the basics of bridge I have used to teach friends and family about the game. Contains an explicit bidding tree for SAYC.

    Bridge articles. Some short articles I wrote to teach advanced bridge situations, e.g. squeezes and coups.
