Éducation
  • Post-doctorat en biogéographie à UQAR
  • Post-doctorat en écologie evolutive à University of Canterbury
  • Doctorat en écologie evolutive à l'Université de Montpellier II
  • Maîtrise en écologie et épidémiologie du parasitism à l'Université de Montpellier I

  • Recherche
    Mes questions centrales sont:
  • comment la variation spatio-temporelle des interactions biotique contribue à la distribution spatiale des propriétés écosystemiques
  • comment intégrer la variabilité des interactions dans les approches de conservation et de gestion (notamment du risque infectieux)
  • comment intégrer différents domaines de l'écologie pour développer des méthodes numériques permettant de prédire la structure des interactions entre espèces sachant que les observations empiriques sont difficiles/couteuses/rares.
