Ma recherche se focalise sur la modélisation à l'échelle de l'atome des propriétés chimiques des matériaux naturels. Plus particulièrement, mon but est de comprendre les mécanismes élémentaires de fractionnement des isotopes.

Au sein du GET, je travaille avec les chercheurs de la Thématique "  Géochimie des Isotopes stables Non-traditionnels" (GIN)

Membre du conseil de laboratoire du GET
