Douglas Wallace is a professor in the Department of Oceanography at Dalhousie University, Nova Scotia, and holds a Canada Research Chair (Tier 1) in Ocean Science and Technology and a Canada Excellence Research Chair (CERC) in Ocean Science and Technology. He is also the Scientific Director of MEOPAR (Marine Environmental Observation Prediction and Response), a national Network of Centres of Excellence based at Dalhousie University (Halifax, Nova Scotia).

He studies the distribution of specific chemicals in the water column to elucidate the complex biogeochemical processes that link the ocean and the atmosphere, and is developing new analytical and robotic technologies to measure changes in nitrogen, oxygen and carbon in our oceans, both natural and human-induced.

He has made significant scientific contributions to his field through the Intergovernmental Panel on Climate Change and the U.S. Department of Energy, where he developed the first survey to measure the global distribution of fossil fuel carbon in the oceans.

Céline Guéguen is a professor in the Department of Chemistry at the Université de Sherbrooke since 2019 and a new member of Québec-Océan. With her academic background in chemical oceanography and aquatic biogeochemistry, she pursues her research on the cycling of dissolved organic matter in marine and continental environments.

Her research team is interested in biogeochemical processes in aquatic systems and particularly in polar regions. It develops innovative analytical methods for the characterization of dissolved organic matter and the detection of trace metals in aquatic systems such as rivers, lakes, reservoirs, marshes, estuaries and oceans. The objective is to better understand how organic matter influences the fate, transport and bioavailability of trace metals in aquatic systems.
