I am an Astronomer working at LESIA/Observatoire de Paris in France, and specialize in the exploration of the solar system and planetary environments.

In particular, I study the tenuous atmospheres of the Solar System (especially Mars, Pluto, Triton, Io) and their interactions with the surfaces, at small and large scales. I seek to understand how these atmospheres work in order to define the past and present climates on these bodies and to predict and interpret different observations. To do this, I develop and use sophisticated numerical climate models, thus modeling the environment of these exotic worlds, and I compare simulations to observations. I am also involved in space exploration via observation campaigns with space telescopes (HST, JWST...), data analyses from mission instruments, e.g. from Perseverance (SuperCam) and New Horizons, and via the preparation of new interplanetary missions.
Aside from research, I teach general physics, astronomy and planetary science.

Short Vitae
  • In April 2021, I was recruited on my current permanent position at Observatoire de Paris.
  • Between 2018 and 2021, I was a PostDoc at NASA Ames Research Center (Mountain View, CA, USA), with Melinda Kahre, working on the modeling of Mars Climate.
  • Since January 2018, I am a NASA PostDoc at NASA Ames Research Center, with Melinda Kahre.
  • Between 2014 and 2017, I was a PhD student in Planetary Science, Astronomy and Astrophysics at Laboratoire de Météorologie Dynamique (Université Pierre et Marie Curie, Paris, France), under the supervision of Francois Forget.
    I completed the PhD degree in september 2017 and received the 2018 PhD Prize «Aguirre-Basualdo» for Best Science Thesis from the Chancellerie des Universités de Paris.
    PhD Research topic : Analysis and preparation of atmospheric and surface ice observations of Pluto by spacecraft NASA New Horizon, using a Global Climate Model of Pluto.
  • Between 2012 and 2014, I was a research engineer in the planetology team led by Francois Forget at the Laboratoire de Météorologie Dynamique (Université Pierre et Marie Curie, Paris, France). Amongst other projects, I have been developing tools for the Entry, Descent and Landing of the Martian spacecraft ExoMars and InSight.
  • In 2012, I obtained a double MSc - Engineering degree from both Ecole Centrale de Nantes and Cranfield University (England), in Astronautics and Space Engineering. While I was at Ecole Centrale de Nantes in 2011, I was hired as a three-month research intern at LATMOS (Laboratoire atmosphères, milieux, observations spatiale).
