My research activities focus on the past climate of Earth and the climate of exoplanets

My expertise spans atmospheric chemistry, from 1D and 3D atmospheric modeling to the interpretation of atmospheric observations (JWST and the future Ariel mission). I developed the photochemistry module for the Generic Planetary Climate Model, the French Global Climate Model hosted at LMD, and I am now leading the development of the upper-atmosphere component within the model through the EXOTOP project. I also work on the interpretation of JWST observations of mini-Neptunes, including the submission of JWST proposals, and I am involved in the Ariel mission through the chemistry working group and the organization of the Ariel School since 2021.
