About me

I am a CNRS researcher at the Lagrange laboratory at the Côte d'Azur Observatory in Nice. My main research interests are the dynamical evolution of planetary systems, from their formation to their observation. I have studied the long-term stability of planetary systems both numerically and analytically. I also work on untangling the history of exoplanetary systems to constrain their formation and current configuration.

You can find my publication list on ADS here.

I completed my Ph.D. in June 2019 at the Ephemeris and Celestial Mechanics Institute (IMCCE) of the Paris Observatory under the supervision of Jacques Laskar and Gwenaël Boué. I mainly worked on the development of simple criteria to determine the stability of exoplanetary systems. In 2019, I joined as a postdoc the planet formation group of Anders Johansen at Lund University and then at the Globe Institute in Copenhagen. I joined the Côte d'Azur Observatory in 2023.
