The Zentrum für Soziale Innovation (Centre for Social Innovation), ZSI in short, is a transdisciplinary social science research institute. The Technology and Knowledge Unit (T&W) focuses its research and development activities on the potentials and limitations of emerging technologies and their diffusion in technologically mediated settings for the benefits of society. A core activity of T&W is the impact evaluation of socio-technical projects and their interactions with social innovations. Since 2011 T&W researchers have also been involved in studying and implementing citizen science activities; since 2017 they have studied and promoted the transition towards a more sustainable production, consumption and lifestyle in several bioeconomy projects. Participatory and transdisciplinary research methods and open science are key tools of the methodological repertoire of this interdisciplinary group.
