Climate scientist at CNRS

CONTACT

I am a CNRS research scientist working at the Climat, Environnement, Couplages et Incertitudes (CECI) lab located at the European Center for Research and advanced Training in  Scientific Computation (CERFACS) in Toulouse, France

I am interested in the role of the ocean and sea ice in climate variability and predictability on time scales of few seasons to several decades. My initial research interest focused on better understanding the mechanisms of variability of the Atlantic Meridional Overturning Circulation (AMOC), its predictability and impact on climate. I also worked on seasonal to decadal predictions of ocean and sea ice.

My current research is articulated around the following topics:

  1. Arctic ocean and sea ice response to climate change
  2. Improved modelling of the Arctic sea ice in Climate models
  3. Quantifying and explaining future AMOC changes
