I am a virologist with a special interest in the study of the fundamental mechanisms of virus multiplication and their links to human health. I have a dual medical and scientific background that allows me to address both the fundamental aspects of virology and medical issues. My research focuses on the study of the replication mechanisms of the respiratory syncytial virus (RSV). My team is particularly focused on the understanding of viral factories, membrane-free viral-induced compartments, which host the central steps of RSV multiplication; and on the study of the late phases of viral multiplication (from the transport of new viral genomes to the release of virions). I joined the Pasteur Institute in January 2023 with my team to continue our work on RSV and to bring my medical skills and expertise on RSV to the National Reference Center for Respiratory Infections (including influenza).
