Biologist holder of a doctorate in geostatistics and an HDR (2012), his expertise is in processing ocean colour data in the optically-complex waters of the coastal areas. He has defined an algorithm (OC5) that is now commonly used for assessing the chlorophyll concentration and the non-algal suspended particulate matter in the waters of the North-West European Shelf. This algorithm is applied at Ifremer but also at CMEMS (Copernicus Marine Environment Monitoring Service).
He is involved in two European projects: JMP EUNOSAT (Joint Monitoring Programme for assessing the EUtrophication of the NOrth-Sea using SATellite and in situ data) and Sentinel-3–EUROHAB. The second project, 2018-2021, aims at using Sentinel-3 for assessing the water quality and the Harmful Algal Blooms in the surface waters of the English Channel.
