Research topics

My research is focused on marine macroalgae that play an essential role for the functioning of coastal ecosystems but are also valuable coastal resources of economic interest (food and industrial uses). A part of my research, in the context of massive seaweed beaching along the French coast of the English Channel in Calvados, is to develop an assessment tool for the quality of marine coastal waters based on the use of the isotopic signatures δ15N in seaweed tissues. (co-supervision of a PhD). As part of this environmental topic, I also take part in environmental monitoring of the process of colonization of artificial reefs by macroalgae (RECIF project) and the assessment of the spatio-temporal dynamics of the primary production and biodiversity of the macrophytobenthos in Seine estuary (PROUESSE project). Another part of my research deals with the development of the culture of seaweeds which have an economic interest (food, gelling industries, pharmaceutical, cosmetic industries..). The growing demand from manufacturers for an algal biomass of quality throughout the year while preserving natural resources had led us to develop systems of micropropagation since many years. More recently following the issues of the oyster farming in Lower-Normandy due to excess mortality of oyster spat the last few years culture of macroalgae has been identified as a way of diversification of shellfish farming activities. My research work involves elaborating of systems of algal biomass production from seaweed species with an economic interest (Porphyra, Chondrus, Laminaria..) by exploiting the sexual cells (spores, gametes) produced by seaweeds during their life cycle or by using somatic cells (protoplasts, explants) on the scale of the Petri dish, of a hatchery and of the foreshore (Regional Council of Lower Normandy – Development of seaweed farming as part of the diversification of shellfish farming – Development of hatchery culture phase of seaweeds in support of the NORMAND’ALG project)
