Brigitte Zanda is a professor-researcher at the Institute of Mineralogy, Physics of Materials and Cosmochemistry (IMPMC) of the Muséum National d'Histoire Naturelle and the Sorbonne University Alliance. These fragments of asteroids, the Moon, Mars and perhaps cometary nuclei, detached from their parent bodies by impacts, arrive on Earth loaded with information on the genesis and evolution of planetary bodies. Brigitte Zanda studies the first instants of the solar system and the geology of asteroids through primitive meteorites as well as the geology of the planet Mars through Martian meteorites. She is one of the leaders of the FRIPON (for Fireball recovery inter planetary observation network) and Vigie-Ciel programs, whose main objectives are to monitor the sky for new meteorites and to involve the public in their field research. She is vice-president of the Meteoritical Society, the international learned society that gathers all meteorite experts and amateurs.
