Yes. As part if the application process we need a letter from your supervisor confirming that they are happy for you to participate in the InnoEnergy PhD School. Given the nature of the training courses and the obligatory international placements it would be impossible for you to participate without their encouragement. Your university must also be or become an InnoEnergy project partner.
However, your supervisor is not losing a researcher, but gaining the opportunity to extend the influence of the lab across Europe, increase the lab’s attractiveness to grant-giving and funding bodies, to grow its contribution to international research activities, and to develop its reputation for both innovation and collaborative research. Your participation in the InnoEnergy PhD School can also increase the lab’s innovation capacity, and its ability to turn research results into patented, revenue-generating products and services.
This can be a considerable barrier so it must be clear how to do this and for example if there is some kind of standard agreement that can be quickly signed. And what about if the supervisor is from company, do they also have to sign it?
