The EU-funded project PLATON+ invites researchers, policy makers and business actors to take part in the discussion forum Thinking across disciplines on the project’s web page www.platonplus.net. The online forum gives visitors the opportunity to share their thoughts on different topics related to interdisciplinary research and the importance of socio-economic sciences in policy making. The forum enables to discuss how socio-economic sciences can be applied to single research disciplines as well as to explore how they can contribute to the wider development of European research and policy making processes.
