Après avoir suivi mon Master SML (Chimie de l’Environnement Marin) à l’IUEM, j’ai poursuivi en doctorat au LEGOS à Toulouse. En 2019, j’ai obtenu la bourse Post-Doctoral Scholar à Woods Hole Oceanographic institution (USA). Je rejoins le LEMAR pour 2 ans grâce à une bourse post-doctorale MSCA (BaSIS).
Mes recherches visent à mieux comprendre le cycle du baryum dans le secteur indien de l’océan Austral en utilisant les isotopes du baryum. Je développerai la méthode analytique au LEMAR et effectuerai des mesures dans l’eau de mer et les particules marines de la campagne SWINGS grâce au TIMS du PSO.
