The Open and Reproducible Research Group (ORRG), a collaborative group based at the Institute of Interactive Systems and Data Science, TU Graz and at Know-Center GmbH, uses evidence-based and computational approaches to make research cultures more open, transparent and participatory through new practices and technologies. In our interdisciplinary team we combine competences in philosophy, sociology, and information science with computer science and life science. We research services, policies, and tools to investigate and foster the uptake and evaluation of Open Science practices.
