Grounded in Artificial Intelligence (specifically Constraint Programming), Spatial Planning, and Landscape Ecology, my research focuses on developing and applying innovative approaches to provide decision support for sustainable socio-ecosystem management. In this era of global change, we need more than ever to move towards more sustainable societies. Because underlying challenges are numerous, complex, and intertwined, we need advanced decision-support methods to explore and identify sustainable trajectories for tomorrow’s societies. My research activities are committed to this with a strong focus on tropical forest socio-ecosystems. My current areas of study and partnership are the forest socio-ecosystems of the Republic of Guinea, the restoration of the Mesoamerican Biological Corridor in Panama, and the conservation and restoration of New Caledonian forests.
