Welcome to my academic page! I am an Associate Professor in the Department of Mathematics at Harvey Mudd College and the Joseph B. Platt Chair in Effective Teaching.
I am interested in seeing algebra come alive in discrete mathematics, primarily in combinatorics, graph theory and discrete/convex geometry. I am also interested in enumerative and geometric combinatorics. Below is my work.AWARDS
