Presentation

IRD Researcher at the MIVEGEC lab in Montpellier.

My works are on Mathematical analysis and Modeling of complex systems (or not), with a particular focus on Dynamic Systems. The applications resulting from this work concern (but not only) epidemiology, the evolution of infectious diseases and ecology.
