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.
Chargé de Recherche IRD affecté au laboratoire MIVEGEC à Montpellier. Mes travaux portent sur l'analyse Mathématique et la Modélisation de systèmes complexes (ou non), avec un accent particulier sur les Systèmes Dynamiques. Les applications résultant de ces travaux concernent (mais pas que) l'épidémiologie, l'évolution des maladies infectieuses et l'écologie.
