Ecophysiological approach of marine microalgae and marine primary production: from laboratory experiments to coastal ecosystems.
My research axes:

• Phytoplankton succession and primary production dynamics by developing an ecophysiological approach.
• Ecophysiology of diatoms with a particular interest in the genus Pseudo-nitzschia
• Dynamics of primary production by coupling modulated fluorescence technics and isotopic tracers of carbon targeting access to the primary production at high frequency.
• Effects of pelagos / benthos interactions on the coastal primary production
• Cellular carbon fluxes from carbon acquisition through photosynthesis to TEP and EPS excretions
• Interactions between carbon and silicon metabolisms and the cell cycle
