Our engagement in national and international research networks

Active engagement in national and international research networks is of central importance for each research institution. In particular with regard to more complex social, economic and ecological challenges in future, strengths have to be pooled, synergies generated and interdisciplinary alliances forged. An important element is the close incorporation of companies from industry and economy. It is also our institute which is engaged in different technical and strategic networks, in order to advance main research areas or to achieve improved perception of industrial research institutions such as ours in the public sphere.
