I am a modeler scientist at CIRAD (French Agricultural Research Center for International Development). I contribute to promote the Companion Modeling approach (http://www.commod.org). I am also in charge of CORMAS development, a Framework for Agent-Based Models (ABM, http://cormas.cirad.fr) dedicated for renewable resources management. I am currently based at the university of Costa Rica where I work on water and Climate Change and coffee rust in Central America.
