About Me
I am a fourth-year faculty member at Pacific Lutheran University. My mathematical interests lie in the relationship between representation theory and combinatorics of Coxeter Groups. I spent 5 years studying under my advisor Matthew Dyer at the University of Notre Dame. Before Notre Dame, I spent 2 years in a Ph.D. program at Colorado State University studying linear codes and finite geometries.
