Research thematics:

My interest is in epidemiology of fungal diseases affecting trees in forests and natural ecosystems. recent work has been focused on determining the causes of forest disease emergence in relation with global change, in particular recent evolution in climate and invasion. The main pathosystems have been studying are Phytophthora alni, Chalara fraxinea, oak powdery mildew,  Dothistroma needle blight and Diplodia shoot blight of pines.
