• Math 141 - Calculus I (F06, F07)
• Math 142 - Calculus II (S07, S08)
• MAT 241 - Calculus III (F07)

Western Carolina University:

RESEARCH

My research is in combinatorics, especially matroids and their connections with graph theory. The main topic of my work is gain and biased graphs. These are graphs with additional structure that leads to new graphical matroids. The theories of gain and biased graphs are being developed by my advisor, Thomas Zaslavsky, in a series of papers entitled ``Biased Graphs''.

Papers

• (with Erin McNelis) "Fantasy Baseball with a Statistical Twist", to appear in Mathematics Teacher.

• "Biased Expansions of Biased Graphs and their Chromatic Polynomials", submitted.

• "A Modular Triple Characterization of Circuit Signatures", to appear in Europ. J. Combinatorics.

• Two Generalizations of Biased Graphs: Circuit Signatures and Modular Triples of Matroids, and Biased Expansions of Biased Graphs, Ph.D. Thesis, Advisor: Thomas Zaslavsky.

• "Comments on 'Supersolvable frame-matroid and graphic-lift lattices' by T. Zaslavsky", Europ. J. Combinatorics, 25(2004), 141-144.

• (with Gary Gordon, Jason Leasure, and Sharon Pronchik) "Matroid Automorphisms and Symmetric Groups", Combinatorics, Probability, & Computing 9(2000), 105-123.
