Emmanuelle George-Marcelpoil is a researcher for Irstea and manages a research team specializing in the development of mountain areas. Her research works concern the tourism sector in mountainous areas, in particular the winter sports resorts. Her objective is to question the productive organization of tourism and the complexity of tourist dynamics. The first axis concerns the logics of the actors, productive as well as territorial, in which the articulation plays an essential role in understanding the dynamics of the tourist destinations, and the second axis concerns the anchoring of the resorts. The stake is to characterize the various types of trajectories for the ski resorts and their different dimensions.
