Equipe G3 Hydrogéochimiste et spécialisée en géochimie isotopique, je travaille à l'interface Environnement / Santé et Société. J'ai été nommée conseillère scientifique auprès de la PDG de l'IRD sur le grand défi "Géoressources et Durabilité" (https://www.ird.fr/la-communaute-de-savoirs-georessources-et-durabilite-geod). Spécialiste des contaminants métalliques, des impacts environnementaux et expositions humaines liés aux activités extractives (minières et pétrolières) et plus récemment agricoles, je travaille en interdisciplinarité sur l'analyse des vulnérabilités environnementales et sociales sur des territoires impactés et participe à la co-construction de nouveaux éléments de réponse et des voies de changement avec les populations locales mais également les acteurs publics en charge de la gestion et de la prévention des risques. Mon principal terrain de jeu est l'Amérique du Sud, avec des affectations en Bolivie, au Brésil et en Equateur. Equipe G3
