infectious diseases modelling





fr en

My research aims to improve the understanding and the anticipation of the epidemiological and evolutionary dynamics of infectious diseases by integrating sources of heterogeneity (polymorphism, spatial structuring, anti-infective treatments, health policies) in the multi-level quantitative analysis (from intra-host to public health via transmission) of pathogens such as Ebola virus, human papillomaviruses, multidrug-resistant bacteria, and more recently SARS-CoV-2.
