I obtained a PhD in Life Sciences in 1989 under the supervision of Georges Periquet. My thesis focused on the organization of the genome of two parasitoid wasps, Euplemus vuilleti and Diadromus pulchellus. I joined the CNRS in October 1990 to develop a project to study the impact of haplo-diploidy of hymenoptera on the structure of their genome and the genetic determinants of the viral strategies of parasitoidism and eusocialization that are only found in these organisms. In 1998 and 1999, I was a visiting professor at Carfornie Riverside University, jointly in the laboratories of Brian Federici and Peter Atkinson. On my return to France, from January 2000 to January 2010, I was in charge of the management of a project for the emergence of a research unit associated with the University of Tours and the CNRS, the LEPG and then the GICC. In June 2011, I joined on the Nouzilly site, the UMR INRAE-CNRS Physiology of Reproduction and Behaviour. I was in charge of the creation and management of the Genomic Plasticity and Phenotypic Expression team. At the end of 2020, I decided to close the team and join the Molecular Neuroendocrinology and Reproduction team to continue working on projects related to the programmed genetic plasticity of neurons.
