Philippe GERBER is a geographer with main interests in Land Use and Transport Interaction (LUTI) models, especially those linking interactions between residential and daily mobility, using spatial analysis and econometric tools. He also has strong expertise in survey design and the application of related analytical methods. In doing so, he contributes to a better understanding of spatial mobility behaviours beyond the traditional prism of ‘bounded rationality’, with a focus on individuals’ attitudes, practices, preferences and representations in particular cross-border contexts. He is working at the Luxembourg Institute of Socio-Economic Research – LISER – since 2001, after his completion of his PhD in 2000 about residential mobility in general, and gentrification and urban comfort in particular. He is also lecturer in three different universities: Luxembourg, Aix-Marseille, Lorraine, and research associate of the Image Ville Environnement Laboratory from the Centre National de la Recherche Scientifique (CNRS) in Strasbourg. He was visiting scholar at the School of Urban Planning and the Department of Geography at McGill University, and also at the Faculty of Environmental Planning at the University of Montréal (QC, Canada) up to August 2019. He is also an invited scholar at EPFL (Lausanne, Switzerland).
