I am an Associate Professor of Computer Science at Virginia Commonwealth
University, since August 2020. Prior to this I was an Associate Professor of
Mathematics (also at VCU), where I
often spoke in the Discrete Math
Seminar (and was an organizer for many years).
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.

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 48 coauthors to date.) By clicking below, you can read about some of them.
