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 PhD student at the LTE (ex-IMCCE) laboratory, at the Observatoire de Paris, under the supervision of Jacques Fejoz and Philippe Robutel. Official name:

"Theoretical and numerical study of reccurent dynamics in dynamical systems and application to the N-body problem"

Here is the link to the PhD page. Its main topics: celestial mechanics, dynamical systems, numerical computations.

I'm currently looking for a post-doctoral position anywhere in Europe, from September 2026 onward! If you are interested, you can contact me with the mail on the left.

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).
