Research

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.
