My research focuses on combinatorics, graph theory, and combinatorial matrix theory. I like to count---by that I mean finding concrete counting contexts that lead to clever combinatorial proofs of algebraic identities. Just prior to starting at UWT, I served as Executive Director of the Association for Women in Mathematics. Before that, I taught at Occidental College in Los Angeles for twelve years where I achieved the rank of Professor and served as Department Chair. I have co-authored dozens of research articles but am most proud of my book *Proofs That Really Count: The Art of Combinatorial Proof* co-authored with Arthur Benjamin. It received the 2006 Beckenbach Book Prize from the Mathematical Association of America for outstanding exposition. Currently I co-edit *Math Horizons*, a magazine for undergraduate math enthusiasts. At UWT, I teach the Precalculus, Calculus I, II, & III, Matrix Algebra, and anything else that we develop along the way.
