My primary interests are algebraic and topological combinatorics.
Lately, this means shifted simplicial complexes, eigenvalues of combinatorial Laplacians, and higher-dimensional analogs of spanning trees.
You can see some of my preprints, abstracts, and slides to talks.
Check out the new AMS blog, On Teaching and Learning Mathematics! I'm a contributing editor, working with a fabulous editorial board.
