FIDELIO will train 14 young researchers  for next-generation bone and diabetes researchers. Each ESR will be enrolled in a PhD programme to study for a doctorate and will conduct her/his own individual research project. Interdisciplinary training and implementation of innovative approaches are the key. The training programme and experience of different international research environments with international leaders cuts across traditional data and life sciences silos.
