PE2020 aims to identify, analyse and refine innovative public engagement tools and instruments for dynamic science governance. It builds on the MASIS project (2010-2012), but provides a deeper analysis of engagement tools and instruments through a systemic and contextual perspective. PE2020 will create new knowledge about trends in the field of public engagement in science through conceptual analyses, building an inventory of engagement innovation, piloting engagement practices, and developing a toolkit for evaluating and transferring successful practices.
