Prof. Couture

I am an aquatic geochemist studying coupled geochemical cycles and the fate of elements such as carbon, iron and arsenic in the aquatic environment. I carry out field, experimental and modelling work focussing on lakes, soils and sediments in the north.

I joined the Department of Chemistry at Laval University, in Québec, Canada, as an Associate Professor in February 2018. I teach first-year inorganic chemistry and third-year environmental chemistry.

Prior to that I spent 5 years at the Norwegian Institute for Water Research in Oslo, as a senior researcher then as a section leader. I have also spent 2 years as a Research Assistant Professor at the University of Waterloo (Canada).

During my graduate studies at the University of Quebec-INRS (Canada), I carried out an internship at IFREMER (France), and one at Utrecht University (The Netherlands). After graduating I held a Marie-Curie Scholarship at the Center for Environmental Geosciences (CNRS, France), and an FRQNT postdoctoral fellowship at the Georgia Institute of Technology in Atlanta, USA.

My research projects touch on the environmental and aquatic geochemistry of major elements and nutrients, on the modelling of water quality (reactive transport, diagenetic and lake modelling) and on the fate and speciation of metals and metalloids. I am particularly interested in the succession of redox processes taking place across reactive interfaces, such as the sediment-water interface and the oxic-anoxic interface in lakes and aquifers. I specialize in acquiring field datasets on the distribution of elements in the water column, sediment and pore water, and on their interpretation using numerical models. My research is often motivated by its application to solve urgent water quality issues affecting surface waters – such as contamination by trace elements, anoxia, browning and eutrophication - in the context of current environmental change.
