Brief synopsis of current research:
Dr. Pellerin is now investigating more closely mechanisms of toxicity of Persistent Toxic Substances in sediments, on reproduction of marine invertebrates. Her team has now developed a multiparametric approach, using a large number of biomarkers to detect physiological effects of PTS in bivalves. Measures of steroid hormones and vitellogenin-like proteins in gonad as well as their cellular distribution are now correlated to sexual maturation and bioaccumulation in currents research programs of Dr. Pellerin. She has a broad field expertise, working in Arctic as well as in subtropical ecosystems. She has also developed an interesting international network of collaborators from France, Tunisia, Morocco and Mauritania.

Environmental studies are fundamental since we observe an urgent need to develop methodologies to detect disruptions at the endocrine level . In fact, some of the contaminants have estrogenic-like properties and/or can displace sexual steroids on cytosolic receptors, thus interfering with the sexual maturation and gonadal development. These impairments are closely linked to delays or dysfunction of the reproductive processes leading to the reproductive potential in a specific population. Bivalves are a very valuable resource exploited both in the wild and in farms. They also have an ecological importance in the structure of the communities. Any factor that can impair the reproductive processes could then be suspected to be harmful to the population.
