My research activities have aimed to gain a deep understanding of the coupled C-N-H2O cycling in forests, by linking different scales of investigations, i.e., from the tree to the ecosystem, and methodological approaches (e.g., stable C and O isotopes in leaves and tree rings, eddy covariance data). During my Marie Curie fellowship at the CREAF I will focus on tree canopies and their role in altering the chemical composition of precipitation and, consequently, the nutrient cycling within forests. I will explore the biological diversity hidden in the canopies, particularly bacteria, and its role in processing the atmospheric N.

Our group (LSCE) have estimated the global budget of phosphorus (P) in the atmosphere by quantifying various sources of P with the uncertainties quantified. Using a new approach based upon the mass balance of P, the emissions of P from biomass and fossil fuel combustion were estimated, which were higher than all previous estimates due to inclusion of P emitted in all phases and particle sizes. As a result, a near closure of the P budget was achieved in the atmosphere.
