Research interests

I’m a global an environmental scientist studying the interactions between terrestrial ecosystem dynamic and environmental changes (climate, land use,..) more specifically the dynamic impacts on carbon, water and energy cycles at scales ranging from the ecosystem to the globe. I primarily develop and subsequently use process-based land surface models in combination with site-scale and satellite observations to unravel  the physical and biogeochemical responses to anthropogenic perturbations.  A wide array of data assimilation techniques enables me to make the best use of both models and data.  My research is aimed towards understanding : (i)  the fate of the terrestrial carbon sink and its main drivers , (ii) the coupling of, and the interaction between, the water and carbon cycles in the soil-plant-atmosphere continuum, and (iii) the sensitivity of future climate model projections to ultimately enhance our ability to mitigate and/or adapt to global change including all  feedbacks between  terrestrial ecosystems and the climate. Over the years, I have focussed on a multitude of topics which required me to invest time and resources in developing numerical methods and models across spatial and temporal scales. My most satisfying main contributions, often going beyond the –at that time- state of the art  are  :

 

Prospective students

Over the years I have enjoyed supervising tens of Master, PhD and postdocs of which several got competitive positions in academia, governmental bodies and industry.  If you have a Master or PhD degree in mathematics, physics, computer science, meteorology, plant physiology, or related topics, and find my research exciting, please, send me your cv and a motivation letter. If I share your vision, I may contact you to discuss your next research position at the LSCE. I believe the LSCE provides an intellectually stimulating environment for high-level research and is a lively science hub bringing together over 200 climate modelers and experimentalists from over 30 nationalities.

 

Institutional responsibilities

I am currently the Team leader of the "Modeling the continental surfaces and interfaces" team (around 30 researchers) and the Project Manager of a project dedicated to the development of the global land surface model, ORCHIDEE (the land surface component on the French IPSL Earth System Model), that gathers more than 100 Research scientists, post-docs and PhDs at several French institutes and universtities outside of France (Europe and China).

Scientific Publications

I have been involved in a wide range of environmental studies, focussed on various aspects of the carbon, water and energy cycles and including many collaborators across the world. I published over 110 papers in peer reviewed journals, including high profile journals (h-index of 40). As I still very much enjoy working on the nuts and bolts of models and numerical methods, I like to contribute to the technical aspects of the papers published by my students, post-docs and collaborators.
