Présentation

Jeune chercheur au CNRS, je m’intéresse à la minéralogie des matériaux primitifs du système solaire afin de mieux comprendre l’évolution des réservoirs chimiques du disque protoplanétaire ayant donné naissance à nos planètes. Mon parcours, de ma thèse au laboratoire UMET de l’Université de Lille à mes expériences postdoctorales au Lunar and Planetary Laboratory en Arizona et au Laboratoire de Géologie de Lyon : Terre, Planètes, Environnement de l’Université Jean Monnet à Saint-Étienne, m’a permis de développer une expertise approfondie en microscopie électronique à balayage et en transmission, en analyse quantitative de matériaux complexes, ainsi qu’en traitement et modélisation de données expérimentales sur Python et Matlab, allant de la déconvolution de spectres à la modélisation des interactions électrons-matière. Ces compétences me permettent d’étudier et de quantifier des objets naturels, terrestres et extraterrestres, hétérogènes à l’échelle micro- et nanométrique, et d’apporter des outils méthodologiques robustes pour leur caractérisation. J’associe cette caractérisation fine parfois jusqu'à l'échelle de la substitution dans un réseau cristallin, à des modèles physiques et thermodynamiques afin de reconstituer les conditions de formation des minéraux constitutifs de ces objets. C'est cette approche méthodologique qui me permet d’aborder les grandes questions concernant les réservoirs chimiques du système solaire primitif et l’environnement nébulaire, notamment la quantité d’eau dans le gaz, la composition chimique et le rapport poussière/gaz.
