Yoan Miot is an assistant professor of urban planning and development at the École d’Urbanisme de Paris (Paris School of Urban Planning, affiliated with the Université Paris-Est Marne-la-Vallée) and a member of the mixed research unit LATTS (Laboratoire Techniques, Territoires et Sociétés — Techniques, Territories and Societies Laboratory; UMR CNRS 8134). Since his PhD research, his work has focused on the problems encountered by urban-planning professionals in struggling French cities. This research has triggered interests in the characterization of the sociospatial dynamics of these areas – notably via work on the concept of urban shrinkage – and in various projects on the ground, depending on the contexts and problems encountered by the actors involved (housing, economic development, energy).
