PhD research

My main research interest concerns the planetary atmospheres. In particular, I mainly study the physical processes (e.g. the effect of external forces such as the stellar gravity or the radiation pressure) ruling the dynamic of the gas surounding the planets or satellites at large distances, into the exosphere, with kinetic approaches. Indeed, the exosphere is often assumed collisionless: the motion of particles is mainly determined by the external forces rather than the collsions and/or photochemical processes.

My work is a mix between Hamiltonian mechanics and Physical Statistics in order to solve the Boltzmann equation for specific cases.

My work is dedicated to the Rosetta mission especially modelling of the plasma of the inner coma with a kinetic approach and data analysis of the mass spectrometer ROSINA/DFMS.
