Geoffrey is a Professor in Urban Analysis and Modelling, a joint chair of the University of Luxembourg and LISER since 2017. Prior to that, he was an Associate Professor for GIS and Planning at the University of Luxembourg and Director of the Master in Geography and Spatial Planning for about a decade. Geoffrey is a geographer by training but has always been in close contact with economists, planners, as he appreciates the inter-disciplinary of collaborations. In particular: he was an Associate Fellow and an FNRS Research Associate at the Centre for Operations Research and Econometrics (Louvain-la-Neuve, BE), as well as a Research Associate at the Martin Centre for Urban and Architectural Studies at the University of Cambridge (UK).

Geoffrey is particularly interested in progressing geographical simulation and spatial analysis methods to understand cities, the emergence of urban forms and land use - transport interactions, which hopefully will support decision-making towards a more sustainable future.
