Sander works as an urban psychologist in the field of urban development, among others for Stipo and Stichting Thuismakers Collectief. As an urban psychologist he does research on the relation between human behaviour and the build urban environment. Recurring themes in his work are the transition between private and public space (the stoop), feeling at home (why do people feel at home?), communities and social networks. He works mainly for housing corporations, municipalities and developers to create places where people feel pleasant, experience a sense of ownership and maybe even feel at home.
