I can summarize my activities with “observing marine ecosystems and biogeochemical cycles using bio-optics”. I work on PFT retrieval from inherent and apparent optical properties. I study CDOM dynamics and its retrieval from remote sensing. I work also with radiometry measured by autonomous Bio-Argo floats for characterizing the bio-optical regimes of the global ocean. I participate also to several outreach programs aimed to spread scientific knowledge and advances over the youngest generation.
