I am (full) professor at the Département de mathématiques of the Université du Québec À Montréal (UQAM).
I was Director of the Laboratoire d’algèbre, de combinatoire et d’informatique mathématique (LACIM), a Centre de Recherches Mathématiques (CRM) laboratory (2016-2023).
I am one of the three Directeur-Québec of the du Board of directors of the CMS (Canadian Mathematical Society).
I am member of the steering committee of the Reflection Groups Network.
My research is at the crossroad of algebra and geometry, more precisely I study Coxeter groups, reflections groups, Artin-Tits groups and their relationships to Lie theory, algebraic and geometric combinatorics, representation theory and geometric group theory.
