Future generations face unprecedented challenges; climate change, resource depletion, socio-economic and health inequalities. To address these challenges researchers will need to push us outside their disciplinary comfort zones to think differently about problems and possibly solutions. In other words, researchers have to work together in inter- and transdisciplinary collaborations. This new way of working requires a different skill set than those taught in disciplinary courses. Therefore, in this training participants will learn and experience the different phases of these complex collaborations. The course is designed for participants to go through the different phases of these complex collaborations: disciplinary grounding, perspective taking, finding common ground and integration. We combine both theory and practise to train collaborative skills.
