Isabelle, Merle


Agronomie, phytopathologie, agroécologie, modélisation


Mes travaux de recherche s’appuient sur des essais de terrain et sur la modélisation pour étudier l’effet du microclimat et des pratiques agronomiques sur les maladies, ravageurs et pollinisateurs des agro-écosystèmes tels que les systèmes agroforestiers à base de cultures pérennes tropicales. Je m’intéresse aussi au développement d’outils d’aide à la décision incluant ces facteurs environnementaux ainsi que la composante socio-économique grâce à la modélisation multi-agents.
