Research interest

My research is primarily focused on the fluctuating relationships between plants and their above and belowground environments. It is based on a functional approach of ecology, and deals with aspects of ecology ranging from ecophysiology to ecosystem ecology, from the plant to the global scale.

Key-words: Plant-soil interactions, root ecology, biodiversity, organic matter cycling, ecosystem functions.

Plant and symbiont (mycorrhiza, rhizobia) diversity effects on ecosystem functioning and stability of functions

Plant responses to climate and land-use changes (interspecific and intraspecific variations, diversity of above and belowground plant strategies, diversity of plant responses)

Plant and plant diversity effects on ecosystem biogeochemical cycling (soil organic matter breakdown and stabilisation, carbon storage in soils, priming, nutrient cycling).

Ecosystem functioning in conditions of land-use change (e.g. causal relationships between agro-ecological practices and agro-system functioning)

Ecology of root systems (links between root traits and plant and ecosystem processes and properties)
