Current research and/or projects

My interests include the impacts of climate change on planktonic ecosystems and on biogeochemical cycles in Arctic and Subarctic Seas and the development of coupled sea ice-ocean-ecosystem models. I am currently working on the development of coupled 3D ice-ocean-biogeochemical (NPZD-O2-pH) models for the Gulf of St. Lawrence to study the impacts of anthropogenic forcing (e.g. hydro-electric development, eutrophisation, climate change) and climate variability on primary production, aggregation of whale forage species (krill), and on the development of a hypoxic and acid zone in the estuary.
