BIOGRAPHIE

DISTINCTION

THÈMES DE RECHERCHE

My research focuses on the biogeochemistry of phosphorus and nitrogen in terrestrial ecosystems, with a special emphasis on soils. I am particularly interested in understanding how biogeochemical processes in soils change along environmental gradients. For this purpose, I often use stable isotopes as a tool to characterize and trace such processes, both, in controlled laboratory settings and in environmental systems.
