In terms of actual substance, ud’s are indeed experts, and are able to supervise (or co-supervise) a PhD programme. It is precisely by giving them greater responsibility within the PhD programme that young ud’s will be able to develop the relevant leadership qualities. And if they are the primary initiator of a project, have secured the necessary funding, and have taken on the primary supervision role, then being the main PhD supervisor is a highly appropriate role for them. The Young Academy supports the obligation to be supervised by at least two supervisors (the four eyes principle). In this way, 'experienced years' can also be included in the supervision of a PhD candidate by choosing a colleague with more seniority and experience as the second supervisor. If funding and a project of their own are still to come, a ud is already perfectly able to sit on dissertation-assessment committees, wear a professorial gown and hold the title of professor, and act as assistant supervisor for the conferral of a doctorate on PhD candidates whom they have supervised. We are eager to enter the discussion with universities on how to ensure high-quality supervision of PhD candidates by supervisors within all job profiles, and how to enable experience to play a role in the composition of the doctoral supervision team.
