Research interests

My area of research is algebraic combinatorics. More precisely, I investigate the combinatorial aspects in modular representation theory of reflection groups (and of their associated Hecke algebras), and of finite classical groups. I am in particular interested in the connections with quantum groups, via the theory of crystals and canonical bases. Insofar as possible, I like to use methods from combinatorics on words.
