Modelling in agro-ecology 

I am an ecologist / agronomist who uses empirical and modelling methods to study questions at the interface of population, community, agro-ecosystem ecology and farms' performances. I primarily work in tropical cropping systems, but I also study interactions and processes that link natural and agricultural systems. I believe that integration is the strength of agronomy and ecology, because of that belief, much of my work has been and will continue to use models as collaborative tools. I try to draw from diverse disciplines to answer both applied and basic research questions. I developed the SIMBA model (see details). I actually focus on food web and spatial ecology with my colleagues: Elsa Canard, Dominique Carval, Luc de Lapeyre de Bellaire, and Pierre-François Duyck.

I joined the CIRAD research team related to banana, plantain and pineapple in 2005. I now have several ongoing projects in French West Indies and agro-ecosystems across African and Latin America. I am actually working in Costa Rica in CATIE, in the Agroforestry Systems with Perennial Crops Team
