II received my PhD from Nice - Sophia Antipolis University in 1997, with a thesis on Control models in fisheries (in French) prepared at Inria. It was followed by post-doctoral positions in the fisheries field at: IFREMER Nantes, France (1997); Helsinki University of Technology, Finland (1997); Institut de Ciències del Mar, CSIC Barcelona, Spain (1998-1999, Marie Skłodowska-Curie grant).

In January 2000, I obtained a research position at INRA in the Applied Mathematics and Informatics research unit, Jouy-en-Josas, France. I started working on mathematical epidemiology applied to livestock. In 2000, I spent 7 months as visiting researcher in the  Veterinary Epidemiology Group at the University of Edinburgh, Scotland. I later directed my research towards crop protection.

In November 2012, I joined the M2P2 team at the Institut Sophia Agrobiotech and the BIOCORE team, a joint Inria/INRAE/CNRS/Sorbonne Université team, in Sophia Antipolis. I am part of the MathNum division at INRAE.
