In a sustainable coastal management context, I try to understand and estimate the shares of natural and anthropogenic stresses in the processes that continually (re) structure this natural heritage. An important part of my work includes the impact of shellfish farming (Bay of Mont Saint Michel-Chausey) on the related "natural" ecosystems. More recently, I developed Arctic polar research on the influence of global warming on the pelagic-benthic coupling. Whatever the place of study, I try to explain the role of MO aquatic ecological processes (pelagos-benthos coupling, filter-feeder growth, recruitment ...) through the use of biogeochemical indicators (fatty acids, stable isotopes...). At the interface between ecology and (bio) geochemistry, the use of these indicators, coupled with that of other methods such as sclerochronology, shed light on the one hand, on the responses of aquatic systems subjected to natural and anthropogenic pressures and secondly, with the help of in situ and laboratory experiments (hydrodynamic flumes...) to validate and quantify the mechanisms involved. Finally, my faunistical skills on marine invertebrates, particularly polychaete annelid group, allow me, in collaboration with taxonomists, to describe new species of Syllidae and Chrysopetalidae.
L’enseignement se réalise principalement dans le cadre de stages de terrain sur la connaissance et la gestion des anthroposystèmes littoraux :
La formation continue concerne la taxonomie des annélides polychètes et plus récemment les impacts du changement climatique en Arctique :
La diffusion de connaissance concerne ma participation à des évènements type fête de la science, fête de la mer et de conférences grand public.
