Présentation

Domaines de recherche

Je m'intéresse aux assemblages microbiens planctoniques et à leurs relations avec l'écosystème et la biogéochimie. J'étudie donc les facteurs qui influencent leur abondance et leur distribution dans la colonne d'eau. Mon originalité est d'utiliser l'analyse à l'échelle individuelle des cellules pour les étudier, à la fois en laboratoire et in situ.
