About Me
My name is Will Craig. I am currently a postdoctoral researcher under the guidance of Kathrin Bringmann at the University of Cologne, and beginning in July 2024 I will start as an assistant professor at the United States Naval Academy. My areas of interest are combinatorics and number theory, in particular the areas of partitions, qseries and modular forms. I am currently most interested in asymptotic properties of partition counting functions and intersections with new kinds of modular objects.
