A biology graduate from the Université du Québec à Montréal in the early 90s, Patrick continued his education with a Masters at the Université de Montréal. It is through his employement as a research professional at the IRBV (Brisson lab) that he has collaborated on a multitude of studies pertaining to phytotechnologies (restauration of disturbed lands, wetland filtration, bioretention).
