GRK 1508 From common scientific profiles towards an integrated model for a European University Hospital EuCAR Research & Teaching & Clinical Services Medizin & Technik EuCAR Medizinische Fakultät Kardiovaskuläre Forschung Klinische Neurowissenschaften In March 2007, the state minister for Innovation, Science, Research and Technology of North Rhine- Westphalia, released a statement concerning University Medicine and Medical Research. With regards to RWTH Aachen University, an integration of both clinical, research and teaching activities with University Hospital Maastricht in terms of an intense cooperation was viewed essential for future developments and structures aiming at a the first European University Hospital.
