My research investigates the molecular mechanisms governing virus-host interactions, focusing on how viral proteins modulate host cellular environments to facilitate replication and evade innate immune defenses. Spanning positive-sense RNA viruses (flaviviruses) and retroviruses (HIV), my research explores the remarkable functional plasticity of viral proteins. I am particularly interested in uncovering how viral factors extend beyond their canonical roles to reshape molecular interactions, reprogram cellular pathways, and influence the outcome of viral infection. By investigating these often-overlooked functions, I aim to better understand the strategies viruses use to exploit host cell machinery and maximize their fitness. Alongside research, I am deeply invested in scientific community life and mentoring. I actively supervise MSc and PhD students, engage in science communication, and serve on the junior sections of both the French Society for Biochemistry and Molecular Biology (SFBBM) and the French Society for Virology (SFV).
