After the first, very successful peer teaching workshop in 2022, the second two-day intense workshop took place, where the Ph.D. students shared their expertise and methodological knowledge with their peers. The interdisciplinary context of the AdONE Research Training Group allowed everyone to benefit from the other disciplines: Questions were answered in detail, problems were discussed or new methods were applied together. Other perspectives on the own work broadened the Ph.D. students horizons and provided new ideas - either for their own work or joint projects.
