Studies in agronomy and a thesis on Soil Sciences (Montpellier SupAgro) led me to study the dynamics of soil organic matter, i.e. the effects of changes in soil use and climate change on soil organic matter stocks. My aims are to understand the main mechanisms for organic carbon sequestration in soils. I use the natural temporal and spatial variability of soil properties and experimental manipulations to estimate the vulnerability of agroecosystems to global climate change.

Over the past few years, I have spent an increasing amount of time on the distribution of scientific studies to the non-academic public. I am the webmaster for the Eco&Sols website, scientific video adviser and author of a soil biodiversity game (cf. § publication).
