Research interests

My research interests lie in unraveling the interplay between lake physics and lake biogeochemistry. With a broad background in environmental sciences and a PhD in aquatic physics, I am particularly interested in the role of physical processes (hydrodynamics, turbulence, heat exchange) in the transport and fate of dissolved, particulate, and living constituents, within the context of human disturbances (climate change, contamination, overtourism). My current research focuses, among other aspects, on turbulent processes in Lake Geneva and their implications for biogeochemical fluxes, as well as on the sensitivity of mountain lakes to anthropogenic pressures. Additionally, I aim at developing science communication initiatives with the public to promote a deeper understanding of our freshwater ecosystems and raise awareness about their importance in our society.
