Climate projections differ between climate models, both on the amplitude of the projected warming and on the associated precipitation changes. The broad goal of my research is thus to better evaluate climate models and the credibility of their projections. To do so, it is necessary to evaluate the representation by climate models of physical processes that are both key for climate change and source of dispersion between models. Testing models capacity to respond to past climate variations is also informative on the credibility of models to simulate the future climate change.
The originality of my research in this context is to exploit measurements of water isotopic composition. Water can has different isotopic species (H216O, H218O, HDO or H217O) whose concentration is impacted by phase changes during the water cycle.
My work follows 3 main directions:
- Exploiting isotopic measurements to better evaluate convective and cloud processes in the tropics
- Exploiting isotopic measurements to better evaluate land hydrological processes
- Exploiting paleo-climatic isotopic archives to better evaluate models response to past climate variations
The French project CONV-ISO (studying convective and cloud processes during the MJO and evaluating their representation in climate models by combining humidity, cloud and water isotopic measurements) is from February 2013 to February 2017.
Post-doc at CIRES (Boulder, USA)
under the direction of David Noone.
PhD thesis at Laboratoire de Météorologie Dynamique (Paris, France)
under the direction of Sandrine Bony and Jean Jouzel, on water stable isotopes and their applications to study the water cycle and climate variations.
This thesis has been awarded the Prix André Prud'homme by the French Meteorological Society, the Prix Le Monde of academic research, and the Prix of the best PhD thesis by the EADS foundation (small moovie summarizing my thesis).
