I am an Associate Math Professor at Virginia Commonwealth University, where I co-organize the Discrete Math Seminar. My research interests are mainly in graph theory and algorithms, but I'm also interested in most areas of discrete math. Here's my cv. Below are links to my papers, talks I've given, and slides from some of the talks. The best way to reach me is via email: dcranston at vcu dot edu


Download: A Guide to the Discharging Method
This 77-page tutorial (lecture notes with many exercises) that I wrote with Douglas West aims to illustrate and demystify the discharging method, which is most well known for its central role in the proof of the 4 Color Theorem.

I've had the privilege to collaborate with many great people. (I have 43 coauthors to date.) By clicking below, you can read about some of them.
