About me

Hi! I'm a long-time space and physics enthusiast, and I had the chance to realize my dream of... well, not going to space, but studying it!

Currently, I am a postdoctoral student in the "Nonlinear Dynamics" team of the Centre de Physique Théorique, in Toulon University.

I defended my PhD thesis in September 2026 at the LTE (ex-IMCCE) laboratory, at the Observatoire de Paris, under the supervision of Jacques Fejoz and Philippe Robutel. Official name:

"A three-body waltz: numerical search of recurring dynamics in the three-body problem"

Here is the link to the PhD page. Its main topics: celestial mechanics, dynamical systems, numerical computations. And a link to the PhD thesis (not definitive version).

Studies

Before starting my PhD, I studied theoretical physics at the ENS, followed by a final master year at the Observatoire de Paris, with an emphasis on the mathematical aspect of astrophysics. I studied computer science as an minor of the ENS diploma, especially compilation, reactive programming, computational topology and computer graphics (courses at the Informatics Department of the ENS, and the MPRI).

Around research

Organizing conferences and seminars

For talks I gave, see here.

Scientific outreach

  • Science outreach at the Cité des Sciences et de l'Industrie

  • A introductory roleplaying game (one-shot) about celestial mechanics! Currently in development and private testing.

  • Podcast with Les Petits Reporters des Sciences (link in french)
