My research interests are primarily in graph theory, but I am also interested in other topics in combinatorics,
theoretical computer science, cryptography, and coding theory. Many of these topics have applications to
computer science and the social and biological sciences.
Exposition and other mathematical or related material that I have produced.
The International Mathematical Union has a call
to all mathematicians to make available electronically as much of their work as feasible. To support this ideal,
I have posted preprints of publications and other exposition above.
