I'm a sixth year graduate student in the Brown University math department, working with Professor Richard Schwartz.

Research Interests: I'm currently interested in discrete dynamical systems, particularly a variant on billiards in which the particle erases walls as it hits them; details and pictures are available at the linked page. I'm also looking at the sandpile problem on finite hexagonal graphs. I've previously done work on various isoperimetric problems, as an undergraduate working under Professor Frank Morgan at Williams.
