After a Master's degree in Biology, Evolution and Environment (University of Montpellier II), then a Master's degree in Sociology (University of Perpignan), I passed a PhD in Biology (University of Perpignan), at the Laboratory of Tropical and Mediterranean Biology and Ecology (BETM UMR 5244 CNRS-EPHE-UPVD). My research has developed on mate choice and mating strategies in a monogamous parasite, Schistosoma mansoni. I was able to analyze the different facets of monogamy and to test the presence of multiple mating using the molecular tool. Equipped with skills in evolutionary concepts, behavioural ecology, statistical and molecular tools, I was recruited in 2010, during my year of ATER, at the University of Poitiers as an assistant professor. Since being recruited, I have taken on many collective responsibilities in teaching and research and had the opportunity to develop my research project on the causes and consequences of genetic diversity. If I have been interested for a long time in mating systems in this context, today I am developing a project on senescence.
