Research projects within this focus area examine the relationship between political regulation and governance of housing provision, the production and management of housing, and the everyday social practices of dwelling.
Our work at SET-Mobility aims to explore the socio-ecological transformation of urban mobility systems while also contributing to this transformation process in practice.
Digital geographies research focuses on the intersections between digital technology and space, examining how the economic, cultural and political constitution of digitalisation occurs through and produces global and local geographies.
Geographies of economization critically examine both the theoretical assumptions of market-based thinking and its political and practical potential to address societal challenges.
This research focus addresses the demands placed on science in the face of multi-scale crises: to take the vitality of the non-human world seriously and to further develop post-anthropocentric perspectives conceptually, empirically, and practically.
This research focus examines how the complex interrelationship between spatial developments, social change, and environmental transformations can be translated into educational processes.
