YUFE4Postdocs (Y4P) is an an innovative training programme developed by the Young Universities for the Future of Europe (YUFE) Alliance in the context of its R&I agenda. Two calls aim for the appointment of 51 researchers in nine YUFE universities. Postdocs can freely define their project connected to Urban opportunities and challenges, in one of the 4 focus areas: sustainability; digital societies; citizen's wellbeing; and European identities. As important components of community engagement, interaction with stakeholders runs as a red thread through the programme. Stakeholder interaction is manifested within the selection procedure, research execution and in the structured training. The selection process pilots a novel approach assessing applicants on a broader and qualitative set of selection criteria, including stakeholder representatives. Incoming postdocs in a YUFE Host University spend a flexible 6 months stay in a YUFE partner university with the objective to set up or develop research collaboration. Additionally they can undertake an intersectoral secondment in a public or business context: nineteen city and business organizations involved in the programme can assist with this through their network of members and partners. The Y4P Training programme contains a solid pillar on stakeholder development, and a varied offer of training sessions jointly offered by the partner universities, routed in the DIOSI and Inno4YUFE projects. As such Y4P aims to (1) empower future proof researchers, skilled to work in interdisciplinary environments, together with stakeholders; (2) set a standard for a next generation research training; (3) foster bilateral and multilateral collaboration across the Alliance and (4) support the development of a true European (research) University.
