Je suis chargée de recherche au CNRS depuis 2014, après une thèse réalisée au National Oceanography Centre (Southampton, U.K), et deux post-doctorats, un aux Etats-Unis à Rutgers University (New Brunswick, NJ) puis de nouveau au National Oceanography Centre. Je suis arrivée au LEMAR début 2013 grâce au programme ANR RPDOC BITMAP.

Mes activités de recherche ont comme objectif très général de mieux comprendre la distribution et le rôle des métaux traces dans l’océan. Ces métaux, très peu abondants dans l’océan, et donc difficiles à mesurer, ont une importance capitale dans la régulation de l’écosystème marin et dans le fonctionnement de la pompe biologique de carbone. Je m’intéresse à la forme particulaire de certains de ces métaux traces, moins bien connue et nettement moins étudiée que la forme dissoute. Je mets en place une stratégie combinant des campagnes de terrain (Atlantique Nord, Océan Austral) à des études de processus en laboratoire permettant de mieux comprendre les processus régulant les échanges entre les compartiments dissous et particulaires. Je coordonne le projet ANR BIIM (2019-2023), et co-coordonne le projet ANR SWINGS (2020-2024).

Je co-encadre actuellement les thèses de:

Natasha van Horsten (en cotutelle avec Stellenbosh Univ., Afrique du Sud): Seasonal Characterization of Fe-binding ligands and Fe speciation in the Southern Ocean

Corentin Baudet: cycle biogéochimique du fer le long de la section GEOTRACES GS02 SWINGS

Et supervise les postdoctorats de:

David Gonzalez-Santana: investigating the impact of shallow hydrothermal vents on biogeochemical cycle of trace elements – focus on dissolved iron

Maria-Elena Vorrath: investigating the impact of shallow hydrothermal vents on biogeochemical cycle of trace elements – focus on particulate trace elements

Wen-Hsuan Liao: impact of the dissolution of particulate iron of sedimentary and hydrothermal origin using an experimental approach

Emmanuel Laurenceau-Cornec: impact of the dissolution of particulate iron of sedimentary and hydrothermal origin using a modelling approach
