“Multidisciplinary use of cohort studies in nutritional epidemiology“ was chosen as an overarching topic, since epidemiological cohort studies form the basis for many research projects in each of the four competence clusters. The program starts with an innovation workshop and continues with presentations of the cluster cohorts, a statistic workshop and lectures on the multidisciplinary use of the studies.The summer school is organized by the competence cluster Diet-Body-Brain (DietBB), Bonn.
