Research Interests


I am a geochemist studying coupled geochemical cycles in lakes, soils and sediments, with a focus on boreal and arctic environments. 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 cascade 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 global change.
