Bio

I received my education in the fields of biology (BSc and MSc, Université Laval, Québec City) and water science (PhD, INRS – Centre Eau Terre Environnement, Québec City). My research expertise and interests combine environmental physiology and aquatic ecotoxicology. Early on, my research activities aimed at assessing the interactions between fishes of socio-economic and/or cultural importance and their environment. Prior to joining River Institute, I served as a Post-Doctoral Research Associate at two institutions: The Virginia Institute of Marine Science (Gloucester Point, VA, USA), where I studied the effects of hypoxia, temperature and a bacterial disease on striped bass; and at Carleton University (Ottawa, ON), where my research assessed the impacts of climate change on inland fisheries of the tropics.

Research Interests

Encompassing freshwater, estuarine and marine species, my research program focuses on the effects of environmental stressors on the physiology and overall condition of fishes, and the ecological repercussions of these responses.
