Research Interests

My research interests are in Coxeter groups, Hecke algebras, algebraic combinatorics and connections between group theory and automata theory. I also enjoy teaching mathematics at all levels and helping to make the joy of mathematics accessible to as many people as possible.

Here is my CV.
