Je suis responsable technique de la plateforme de spectrométrie de masse de l’ISEM.
Je gère les analyses isotopiques en mode organique.

Mes recherches ont pour objectif
la reconstitution des changements climatiques et plus spécifiquement des variations de saisonnalité et de variabilité inter-annuelle grâce à l’analyse isotopique de dents de mammifères marins ou continentaux.
