I co-head the “Genome Dynamics” research team at the Centre de Biologie Intégrative in Toulouse, of which I am also Deputy Director. After a PhD in Microbiology in Toulouse and a post-doctoral stay at Oxford University in England, I joined the CNRS in 1998. My work focuses on the organization of bacterial genomes and their dynamics during the cell cycle, in particular during the final stages of chromosome segregation linked to cell division. With my collaborators, I discovered the importance of chromosome polarization along the replicative axis for segregation processes, and described the elements involved at the molecular level, followed by the segregation pattern in this region at the cellular level. I was awarded the CNRS bronze medal in 2006.
