Antoine Sciandra has specialized in the study of the ecophysiology of microalgae, notably through a laboratory experimental approach, with two objectives: 1) to understand its response to global change and the consequences on ocean biogeochemical cycles and 2) to optimize the production of target metabolites. To this end, he has developed a highly sophisticated culture system, the PhytoPulse, that produces high-frequency data needed to validate mathematical growth models. He has also set up a platform (Full Spectrum) that allows experiments to be carried out on l microalgae culture ponds. He has supervised about 15 PhD students, produced 68 papers (H-index 25), participated in 10 oceanographic campaigns, and contributed to various projects on the valorization of microalgae (ANR : Shamash, Factor4, Purple Sun, Ctrl-AB, Photobiofilm Explorer; PIA : OPALE; FUI : Salinalgue). He is also associated with 4 patents, and was director of LOV for 10 years.
