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.

Investigate fine scale sex dispersal with spatial and genetic analyses

The preregistration "Investigating sex differences in genetic relatedness in great-tailed grackles in Tempe, Arizona to infer potential sex biases in dispersal" [1] presents the analysis plan that will be used to genetically and spatially investigate sex-biased dispersal in great-tailed grackles (Quiscalus mexicanus).
Several hypotheses implying mating systems, intrasexual competition or sex-related handicaps have been proposed to explain the diversity of dispersal patterns between or with...
