Junior research group

© Fraunhofer WKI | Manuela Lingnau

The Fraunhofer WKI and the Institute of Building Materials, Concrete Construction and Fire Safety (iBMB) of the Technische Universität Braunschweig offer young scientists the possibility of setting up a joint working group in order to develop innovative solutions for the buildings of the future. A multidisciplinary junior research group is currently investigating the long-term behavior and durability of wood-hybrid systems for load-bearing structures in building construction. The junior research group is funded by the German Federal Ministry of Food and Agriculture (BMEL). Project management is the responsibility of the Fachagentur für Nachwachsende Rohstoffe e. V. (German government agency for renewable resources).
