My background is freshwater ecotoxicity, bioavailability and chemical speciation of contaminants from agriculture, urban areas and industry (trace metals, mixtures). I joined IRSN in 2002 first as a researcher in radionuclides ecotoxicology, then involved in the team management since 2008. I took part in several European projects in radioecology (ERICA, PROTECT, STAR, CONCERT) for the development of ecological risk assessment methods of radioactive contaminants and mixtures. As a member of the European Alliance in Radioecology (http://www.er-alliance.org) since its creation in 2009, and its treasurer since 2018, I am also involved in the update of the Strategic Research Agenda for radioecology and its Joint roadmap within the european radiation protection research community.
