Research

The general framework of my research is the study of the geochemical processes occurring at the Earth surface and the role of the interactions between the hydrosphere, biosphere and geosphere on global biogeochemical cycles. Especially my work aims to better understand the role of chemical weathering and physical erosion on the long term carbon cycle. I am also interested in studying the impact of human activities on biogeochemical cycles and in identifying sources of contamination in surface water. To do so I use different approaches and among them I use stable isotopes. My current research focuses on the partition of solutes between surface and groundwater fluxes and in the role of vegetation on the riverine export of solutes.
