Research Interest
Forest ecology Climate change Natural disturbances / Extreme Events
Multi-risks Vegetation dynamics Ecosystem processes modeling
My research is focused on the study of dynamics of natural disturbances (drought, fire, insect outbreaks) and vegetation in forests and agroforestry systems, and their close and complex interactions with climate. The aim is to 1) quantify the impacts on these ecosystems of global warming (including climatic and socio-economic forcings) and the future risks of natural disturbances, and their combined effects, and 2) define optimal land management strategies (prevention and mitigation) to reduce the vulnerability of these ecosystems to global change. To this end, I combine multiple data sources such as forest inventory data, products of remote sensing data with process-based modeling of vegetation functioning and dynamics of natural disturbances.
