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).
My primary area of research is combinatorial group theory, and my favorite themes are Coxeter groups, reflections groups and their related structures. My research program sits at the interface of algebraic and geometric combinatorics.
