Strengthening interdisciplinary work, promoting the exchange of experience between science and practice, utilizing technical-scientific knowledge - these are the main topics of the DGM expert committees. After four years as active spokesman of all DGM expert and joint committees, Prof. Dr.-Ing. Heinz Palkowski of the TU Clausthal-Zellerfeld handed over his office as scheduled at the turn of the year. Dr. Blank Lenczowski of Airbus Defence and Space GmbH, based in Taufkirchen, was elected as his successor for the next two-year term of office. She is the first spokeswoman of all expert and joint committees in the history of the DGM. At the same time, she is the Expert Committee Chair for the Aluminium Expert Committee. We would like to thank Prof. Dr.-Ing. Heinz Palkowski for his commitment and dedicated participation in the joint work of the DGM and wish Dr. Blank Lenczowski a successful start and lively exchange in the DGM network.
