About me
I'm currently CNES fellow at LIRA at Paris Observatory (before at Institut d'Astrophysique de Paris (IAP) --> INRIA Grand-Est Nancy). I use computational methods, including cosmological simulations and orbital integration methods, to investigate the dynamics of globular clusters across cosmic time and diverse environments in order to interpret and reproduce observational data highlighted by the Gaia and Euclid missions. My scientific objective is to understand how globular clusters form and evolve, while also using them as tracers to probe the nature of dark matter.
My doctoral research at IAP focused on the nature of the dark matter and more particularly on the inconsistency of inner dark matter density profiles in dwarf galaxies, known as the cusp-core problem. I performed simulations with the high performance collisionless N-body code, Gothic. This gravitational octree code runs entirely on GPU with adaptive time steps. My high resolution approach is the pathway to high resolution that is far beyond that of any N-body simulation.
Here you will find a selection of popular science articles where I explain my research and related topics in an accessible way:
- CNES news 2025 about Milky Way globular cluster classification
- LIRA press release 2025 about Milky Way globular cluster classification
- CNRS press release 2020 about dark matter within globular clusters
