Curriculum Vitae (last updated: 09/2020)

I am an Assistant Professor and Devon Endowed Professor of Mathematics here at the University of Louisiana at Lafayette. Before coming to Louisiana, I had postdoctoral appointments at the University of Aberdeen, the University of Montana, and Rutgers University.

My research is on the structure of finite groups, especially around a prime p. I tend to think most about fusion systems and their associated homotopy theory and homological algebra, geometries and subgroup complexes of finite groups, and modular representation theory.

Office hours (Spring 2022)
