The diversity of supporting organizations is a strong asset for interdisciplinary and training experience. Collaborative members contribute to the training activities, either as a monitor (e.g. host for internships), collaborators to research (e.g. participant to workshops) or as a trainee (e.g. summer school or training package). Active participation of partners as trainers and trainees in the program improve feedbacks and ensure that the training strategy remains finely tuned to their needs.
