Research Area: Combinatorics and discrete geometry

My research centers on the interplay between combinatorics, geometry/topology and algebra with a special emphasis on matroids and f-vectors of simplicial complexes. Matroids are combinatorial abstractions of linear independence. Their enumerative properties have applications in a variety of fields, including graph coloring and flows, linear coding, arrangements of hyperplanes, and problems in reliability theory. My interest in matroids originally started with the discovery of a close connection between matroids and quotients of spheres by elementary abelian p-groups. More recently, I have used face rings to establish analogues of the g-theorem for simplicial polytopes for a variety of simplicial complexes.
