Education:
2004 – 2009 Laval University, Quebec, Canada Ph.D. in Oceanography Influence de la structure des communautés planctoniques sur la variabilité temporelle et spatiale de la production marine du diméthylsulfure (DMS)

2002 – 2004 Laval University, Quebec, Canada M.Sc. in Biology Production marine de diméthylsulfure au cours du déclin d'une floraison printanière de diatomées dans l'Atlantique Nord-Ouest

1998 – 2002 Université du Québec à Rimouski (UQAR), Rimouski, Canada B.Sc. in Biology - Marine Sciences

Research Interests :
My scientific pursuits include the study of the dynamics of marine sulfur cyling with a specific focus on the climate-cooling gas dimethylsulfide (DMS) and its metabolic precursor dimethylsulfoniopropionate (DMSP). Ocean-atmosphere exchanges of climate-relevant gases of biogenic origin and their variability within a changing climate are the key drivers of ongoing scientific objectives and investigations I am involved in. Fundamental questions related to processses such as ocean acidification (especially in pH-sensitive regions such as the Arctic Ocean) and modifications in the supply of the essential micronutrient iron to oceanic regions along with their impact on plankton communities and the production of DMS are explored through active participation in national and international oceanographic missions and laboratory experiments.
