  • Post-doctorate studies in biogeography at UQAR
  • Post-doctorate studies in evolutionary ecology at the University of Canterbury
  • Ph.D in evolutionary ecology at Université de Montpellier II
  • M.Sc in ecology and epidemiology of parasitism at Université de Montpellier I
  • B.Sc in life sciences at Université d'Évry Val d'Essonne

  • Research

    My central research questions are:
  • How the spatio-temporal variation of biotic interactions contribute to the spatial distribution of ecosystem properties
  • How to integrate the variability of interactions in the approach to conservation and management (namely risk of infection)
  • How to integrate different domains of ecology to develop numerical methods which can allow the prediction of the structure of interactions between species, knowing that empirical observations are hard/expensive/rare
