Bernard de Massy, Engineer in Agronomy and doctor in microbiology, did a four-year postdoc in the United States (NIH, Columbia University) and then joined the CNRS in 1988.In 1998, he created his team, "Meiosis and Recombination" at the Institute of Human Genetics (Montpellier). His projects have led to the discovery and characterisation of several genes essential for recombination between homologous chromosomes in mammals. These results have implications for the maintenance of genome stability and evolution. Bernard de Massy is a member of EMBO, has received the Silver Medal of the CNRS, a prize from the Bettencourt-Schueller Foundation and the Rosen Prize of the Foundation for Medical Research.
