About me

My doctoral research at the Institut d'Astrophysique de Paris focuses on the nature of the dark matter and more particularly on the inconsistency of inner DM density profiles in dwarf galaxies, known as the cusp-core problem. I perform 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 cosmological simulation.

I am also involded in scientific mediations such as the Science festival and Paris Science festival.
