Main Research Fields

I am interested in the formation and evolution of the Solar System. As a geologist/spectroscopist, I am interested in surfaces of planets, comets and asteroids, but I also study the volatiles of comets with my expertise in VIS/NIR spectroscopy. I have divided my research in two directions: 1- Differentiated bodies like the Moon and Mercury to understand the thermal evolution of these bodies through their volcanic history, 2- Small bodies like comets and asteroids because they are more pristine than big planets and can constrain the origin of the Solar System.
