Isabelle, Merle

Postdoctoral researcher

Agronomy, plant pathology, agroecology, ecological modeling



My research involves field trials and ecological modeling to study the effect of microclimate and management practices on diseases, pests and pollinators in agro-ecosystems such as tropical perennial agroforestry systems. I am interested in the development of decision support tools including these environmental drivers but also the socio-economic component through multi-agent modeling.
