Expertise / Responsabilité
paléocéanographie, isotopes stables (carbonates)

Activités
Coté enseignement, j'enseigne en Sciences de la Terre.
Coté recherche, je travaille sur la reconstitution des climats du passé.
Mon sujet de recherche s'attache à reconstruire les variations passées de certains paramètres des océans mondiaux, comme la température ou la salinité. L'outil principal de ces reconstitutions est l'analyse géochimique (isotopes stables, 18O et 13C) des tests de certains micro-organismes carbonatés, comme les foraminifères ou les coraux.
Mes recherches se concentrent plus particulièrement sur les zones tropicales (zone météorologique appelée ITCZ -zone de convergence inter-tropicale), et les variations de la salinité de surface des océans en lien avec le bilan hydrique (précipitation – évaporation).
Les échelles de temps de ces enregistrements couvrent en grande partie la période Quaternaire, allant des variations océaniques subies lors des grandes transitions glaciaires-interglaciaires, aux variations climatiques millénaires, à plus haute résolution.
Récemment, je tente d'élargir mes compétences en appliquant les mesures isotopiques à un autre support que sont les ostracodes, micro-crustacés que l'on peut trouver à la fois dans le domaine marin et dans le domaine continental (lacustre).
Je suis aussi Responsable scientifique de la Plateforme Isotopie.
