I am an oceanographer with a strong expertise on light propagation and light-matter interactions in the ocean. My research activities cover the study of fundamental lightdriven processes in the ocean (e.g. photosynthesis, photo-oxidation), the optical characterization of various substances found in seawater, the description and understanding of the variations in ocean biomass production, the monitoring of light driven carbon fluxes and biomass production from space using ocean colour remote sensing, the development of the related remote sensing algorithms, and the modelling of light-driven processes in the ocean and ecosystem interactions. My research is achieved in the laboratory, in the field and using remote sensing technologies. Part of it is also based on theoretical calculations and modelling. While remote sensing and the related technical developments are central in my research program, my scientific objectives are motivated by fundamental questions on the impact of climate change on marine ecosystems.
