Frans Sengers is a postdoctoral researcher in the Copernicus Institute for Sustainable Development at Utrecht University in the Netherlands. The connecting theme running through his work is transformative change in urban contexts, especially in Asian cities. A key question is how sociotechnical experimentation, institutional change, and path-dependent regimes in cities across the globe coproduce our urban future. His current postdoctoral research centers on eco-city and smart city developments, comparing current activities in Europe and China. Frans previously completed his PhD dissertation on the prospects for sustainable urban mobility in Thailand. E-mail: F.Sengers@uu.nl
