The second student retreat was held online via Zoom from June 3-5. The retreat was organized by the PhD students themselves and was a real success. Dr. Stefan Uderhardt, Prof. Dr. Samuel Huber and Prof. Dr. Gerhard Krönke were invited to give a talk. Additionally, Andrey Kruglov, PI of TRR241, gave insight into his current research topics. Congratulations go to Marilena Letizia & Lucas Kreiß who won the poster awards. Thank´s to all PhD students for the excellent poster presentation at the iRTG retreat.
