Directeur.trice de recherche CNRS

Fabrice Not

I'm a CNRS senior scientist at the Station Biologique de Roscoff. I work on plankton ecology using molecular and microscopy tools. I particularly interested in biotic interactions between planktonic organisms and more specifically symbiotic relationships. I'm trying to understand what are the fundamental biological processes involved in plankton symbiosis and what is the role of such interactions in oceanic ecosystems. Keywords : Plankton, Ecology, Photosymbiosis, Radiolaria, Science Outreach
