I am a marine biologist specialising in coastal ecology, I also teach at the University of Brest. My thesis, on the effects of hydrodynamics on intertidal communities, was carried out at LEMAR between 2017 and 2020, under the supervision of Erwan Ar Gall, Gauthier Schaal and Jacques Grall.
Currently, I am pursuing my research on the functioning of coastal habitats, particularly on rocky foreshores dominated by wrack, maerl beds or eelgrass beds. I monitor and evaluate these habitats by sampling in situ, by Geographic Information System and statistical analysis of data, in the framework of Rebent, DCE and DCSMM monitoring. In parallel, I am collaborating with Wendy Diruit‘s thesis, aiming to use remote sensing (drones, satellites) to accurately describe intertidal habitats.
I am also trained in molecular biology, in order to better understand the taxonomy and population genetics of macroalgae. Furthermore, I coordinate the project “Algae of Brittany and the North-East Atlantic” and participate in the monitoring of Non-Indigenous Species on the European coasts.
