I lead the Aquatic Geochemistry Group in the Department of Chemistry at Université Laval.
My research examines how nutrients and trace elements cycle through boreal and Arctic lake systems, combining intensive field measurements, laboratory analyses, and numerical modeling to better understand and predict ecosystem responses to environmental change.
My expertise
I specialize in acquiring high-resolution field data on element distributions in the water column, sediments, and porewaters, and interpreting these processes using quantitative models. My work is often driven by urgent surface water quality challenges, including trace metal contamination, hypoxia, lake browning, and eutrophication, within the context of global climate change.
Lab values
In my laboratory, I am committed to providing rigorous training in fieldwork, laboratory experimentation, and computer-based modeling, tailored to the needs of each project and student. We foster a collaborative, supportive, and inclusive environment where professionals and students mentor one another, develop independence, and contribute to a welcoming and respectful lab culture.
Background
Prior to joining Laval, I spent 5 years at NIVA (Norwegian Institute for Water Research) in Oslo, first as senior researcher then as leader of the Section for Catchment Processes, developing models for lake and catchment response to environmental perturbations through EU-funded projects. I also held a research faculty position at the University of Waterloo for 2 years.
