Background

I received my PhD from Nice Sophia Antipolis University in March 1997, with a thesis on Control models in fisheries (in French) prepared in the COMORE team (currently BIOCORE), Inria Sophia Antipolis, France. It was followed by post-doctoral positions in the fisheries field at: Laboratoire MAERHA (currently EMH), IFREMER Nantes, France (1997); Systems Analysis Laboratory, Helsinki University of Technology, Finland (1997); Institut de Ciències del Mar, CSIC Barcelona, Spain (1998-1999).

In January 2000, I was recruited as a researcher at INRA (Applied Mathematics and Informatics division) in the MIA research unit (currently MaIAGE), Jouy-en-Josas, France. I started working on mathematical epidemiology applied to livestock and then directed my research towards crop epidemiology.

In November 2012, I joined the Sophia Agrobiotech Institute, M2P2 team, and the joint Inria-INRA-UPMC/CNRS BIOCORE research-team in Sophia Antipolis.

Research

Research interests

Development and analysis of mathematical models in population dynamics
  • Numerical exploration: parameter identification, sensitivity analysis, simulation
  • Mathematical analysis: parameter identifiability, order reduction, stability
Main applications in epidemiology
  • Crops: plant-pathogen/pest interactions; sustainable management of crop resistance
  • Livestock: host immune response to an infection, disease spread in herds
