Research

Doctorate in Mathematics:  University of North Carolina, Chapel Hill, NC.   fall 1995.  Advisor: James D. Stasheff.

Areas of Research :  Algebra and Combinatorics.

I am interested in both graph theory and abstract algebra, particularly in using algebraic techniques to achieve graph theoretic results. My recent work has been primarily with graph polynomials, constructing them and embedding them in algebraic structures sufficiently rich to extract new information from them. I have been able to use Hopf-algebras to derive new identities for the Martin polynomials of both oriented and unoriented Eulerian graphs, as well as for the Tutte polynomial along the diagonal y = x.  Currently, I am considering two problems. One is developing a new graph polynomial that might lead to some insights into the cycle double cover conjecture. The other is constructing a generalization of the Penrose polynomial to address graph coloring questions.
