The mutual one-week research stays serve the conception and preparation of the summer schools, excursions, publications and student projects. During the mutual stays, thematic analyses and results are also deepened. Mutual presentations and inputs on the main topics (e.g. on digitalization in the regions, urban development concepts, etc.) by researchers from AUTH and LUH as well as experts and practitioners on site are intended to fertilize the dialogue. In addition, excursions to case studies are planned (e.g. city administrations, real-labs, etc.). Furthermore, the stays will be used to conduct empirical surveys (e.g. surveys or interviews).
