Prof. Couture

I am a geochemist studying the coupled cycles and the fate of elements such as carbon, iron, sulfur and trace elements in freshwater and terrestrial environments. I carry out field, experimental and modelling work focusing on lakes, soils and sediments in boreal and northern settings.

I joined the Department of chemistry at Laval University, in Québec city (Canada), as an Associate Professor in February 2018, where I hold a Sentinelle Nord research chair and lead the Aquatic Geochemistry Group. I teach 1st year inorganic chemistry, 3rd year environmental chemistry and a graduate-level course on aquatic biogeochemical cycles.

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

My PhD focused on the geochemistry on arsenic in lake sediments, under the supervision of Profs. Charles Gobeil and André Tessier, at the University of Quebec-INRS-ETE (Canada). After graduating I held a Marie-Curie Scholarship at the Center for Environmental Geosciences (CEREGE, CNRS, France) under the supervision of Dr. Jérôme Rose, and a FRQNT postdoctoral fellowship at the Georgia Institute of Technology in (Atlanta, USA) under the supervision of Prof. Philippe Van Cappellen.

My current research projects touch on 1- the environmental and aquatic geochemistry of major elements and nutrients, 2- on the modelling of water quality (reactive transport, diagenetic and lake modelling), and 3- on the fate and speciation of trace elements such as rare earth elements, arsenic, selenium and vanadium in northern aquatic environnements.

In the field, 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, increasing loads of organic matter and eutrophication - in the context of current environmental change.
