I am a CNRS research scientist working in Paris, France, at LMD/IPSL. I am also a research affiliate at LAB in Bordeaux, France.

My research work lies at the interface between astrophysics, climate sciences and geophysics. I develop and use a hierarchy of sophisticated numerical atmospheric models to study the climates of terrestrial planets located both inside the Solar System (Mars, Earth and Venus) and outside (exoplanets). The goal of this work is to explore new worlds, potentially similar to our own, and from that exploration, to get a unique perspective on our Earth.

While astrophysics fascinates me, I am concerned about the human-driven evolution of Earth's climate. My ambition is to help detect and characterize the atmosphere, clouds and surface of terrestrial-size exoplanets. This scientific endeavour would make it possible to study exoplanets potentially similar to the Earth (at least in size, mass and insolation) but which have evolved in a very different environment from our Earth. It is a unique opportunity to put the Earth, its past and future evolution, in a wider context.

Do not hesitate to contact me for questions, collaboration, or if you are looking for a postdoc/PhD/internship project!

Research Topics and Questions

  • Numerical climate modeling of planets and exoplanets. With my colleagues, we develop and use a sophisticated 3-D Global Climate Model (GCM) called "Generic PCM" to simulate all possible types of planetary atmospheres.
  • Theoretical and Experimental Spectroscopy, to characterize the radiative properties of atmospheric gases.
  • What are the possible climates of rocky exoplanets? How does it relate with their potential habitability? How to observe it with telescopes?
  • How to characterize the atmospheres of rocky exoplanets with both low and high-resolution spectroscopy?
  • How close the Earth is from a catastrophic runaway greenhouse? What are the conditions required to form and maintain oceans on Earth, Venus, Mars and exoplanets?
  • Why and how did Earth escape glaciation (a.k.a. Snowball Earth) events?
  • What was the climate(s) and environment(s) of Mars 3-4 billion years ago, while lakes and valley networks were formed?
