Presentation

I am interested in marine planktonic microbes (abundance and activity), and their relashionships with the ecosystem and the biogeochemistry. I therefore study the factors that influence their abundance and distribution along the water column. My originality is to use single cell analysis to study them, both in the lab and in situ.
Je m'intéresse aux assemblages microbiens planctoniques (abondance et activité) 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 de cellules uniques pour les étudier, à la fois en laboratoire et in situ.
