The SFB1552 PhD and postdoc retreat took place for the second time. On October 13 and 14, they met in St. Goar to present their scientific progress and share their methods with each other. In addition to the scientific aspects, the sense of community was strengthened during a joint wine tasting with a cellar tour in Oberwesel. We would like to thank the PhD representatives for organizing the event and are delighted with the lively discussions and deeper cooperation within the network.
