Closer Cities aims to increase the shareability of urban (research) projects. As part of our platform, we would like to showcase the extensive array of existing urban research. We therefore developed the '5 questions to' series in which we ask scientists to briefly reflect on their research and shareability of their insights. By answering the following five questions, you help us – and the visitors of our platform – gain insights into how and why we share knowledge. Your answers will be published on our website, closercities.org. Thank you for participating!
