Paulette Duarte is a senior lecturer in the Institute of Town Planning and Alpine Geography of the Grenoble Alps University, and a researcher in the laboratory of social sciences Pacte. Her research concerns the contemporary city and the actions that aim at its transformation. The definition of the urban spaces (metropolis, urban area, city, district, public place, housing), the understanding of social and urban phenomena at work in these spaces, such as the urban depreciation-valuation, and the analysis of the processes of construction of collective actions to renew these spaces are targeted. Her research mobilizes a sociology of the social representations and the actors of the urban.
