I am an aquatic biogeochemist studying carbon gas (CH4 and CO2) dynamics in and emissions from natural (i.e., lakes, rivers) and man-made/altered (i.e., reservoirs, dammed rivers) water bodies. Currently, I am a Research and Teaching Fellow at the University of Geneva in the Aquatic Physics group at the Department F.-A. Forel for Environmental and Aquatic Sciences.

My research interests focus on two complimentary themes. The first is to understand the environmental drivers of carbon gas dynamics in aquatic systems. The second is to develop new approaches to upscale emissions from the local to regional/global scales, such that these approaches also enable the prediction of how carbon fluxes may be altered by environmental changes. Investigating the drivers of emissions means conducting fieldwork regularly to measure gases and emissions, as well as biogeochemical and physical lake parameters, and various environmental variables. I use these field data to derive mechanistic models that describe gas dynamics and can be used for upscaling and prediction based on climate-related changes to nutrient loading, hydrodynamics, or other lake conditions. I am also currently leading a large-scale project with >80 participants from >20 countries investigating the occurrence of oxic methane production in lake surface waters. This project is within the Global Lake Ecological Observatory Network (GLEON).

I have published 26 peer-reviewed articles and mentored several Bachelors, Masters, and PhD level students over the years. I was awarded a Swiss National Science Foundation Advanced Postdoctoral Mobility fellowship to work at the University of Quebec at Montreal. I have also received a Marie Sklodowska-Curie Individual Fellowship for my project TRIAGE: Trophic state interactions with drivers of aquatic greenhouse gas emissions, which will begin in the coming year.

Finally, I am lecturing in one course and teaching two field courses in the Masters of Environmental Science program at the University of Geneva on aquatic Alpine systems.
