Mes travaux portent sur la compréhension de la régulation du fonctionnement des écosystèmes terrestres en terme de flux de matière (eau, carbone, nutriments…). Initialement centrées sur les écosystèmes méditerranéens, mes activités ont été élargies à d’autres écosystèmes subissant de très fortes contraintes (les hauts plateaux andins). 

My research focuses on the understanding of terrestrial ecosystems functioning in terms of fluxes (water, carbon, nutrients ...). Initially centered on Mediterranean ecosystems, my research activities have been extended to the Andean highlands).

My research focuses on the developmental cycle and the ecological niche of extra-tropical forest trees, both of which are currently challenged by climate change. Identifying the key traits that allow a particular species adapting to its environment and the identifying the constraints on their genetic evolution are the key motivating forces behind my research, which lies at the interface between functional ecology and evolutionary ecology.

I have initiated pioneering work on process-based species distribution models for plants, which I use to study the evolvability of the ecological niche of tree species. My work is deeply concerned by climate change and the models I develop are also used to provide accurate forecast of trees’ distribution for the upcoming centuries.

I am using a combination of modelling (PMP, PHENOFIT), experimental work in both field and controlled conditions, as well as long term monitoring of natural populations to feed my research. I have also founded a national Observatory of the seasonality of biological activities (TEMPO) whose main achievements are a data portal, and the Citizen Science program Observatoire Des Saisons.
