Research interests

My current research activity focuses on the study of the seasonal dynamics of nitrogen fluxes in forest soils in relation to tree functioning and soil microflora. In particular, this involves identifying and quantifying nitrogen uptake by trees during the seasons in relation to microbial mineralization and immobilization activities.

Our studies are based on in situ 15N labelling experiments for flux measurement. The microbial groups involved in these processes are studied thanks to collaborations with Anne Marmagne (INRA Versailles) for the measurements of 15N and Valérie Pouteau for the identification by the PLFA technique (ECOSYS).

Teaching

Most of my teaching focuses on the ecology of plants in ecosystems and relies on field trips: on the campus of the university (L1, L3 BOE, Master BEE), in the forest of Fontainebleau (L1 option biodiversity), in the Alps in Auvergne (Master MEFF), in Roscoff (Master BEE). My work focuses on the recognition of plants in their environment, methods of studying ecosystems, plant biology, physiology and ecology, biotic interactions and soil.
