Lydie Bonal received her education as a physicist. In 2006 she defended her PhD thesis focused on the metamorphic episode experienced by chondrites in their parent asteroids. She then worked in the US for four years: at the University of Hawaii (3.5 years) and at the Department of Terrestrial Magnetism (Washington DC, 0.5 year). She investigated mainly the asteroidal aqueous alteration. In 2011, Lydie was appointed as an associate-astronomer at the Observatoire des Sciences de l’Univers de Grenoble (France), where she has been working on diverse cosmochemistry projects mostly related to asteroidal alteration and its consequences on the pristine characteristics of organics and water.
