The NUCLEUS project is a 4-year, EU-funded project aimed at embedding responsible research and innovation (RRI) in the governance and culture of academic institutions. RRI involves stakeholders throughout the research process to better align outcomes with societal needs. NUCLEUS seeks to change university cultures and policies so that RRI principles like addressing social needs, rather than just research excellence, are prioritized. It involves studies of stakeholder attitudes, communication, and engagement to develop an RRI roadmap for universities.
