The close cooperation of trainees with different study backgrounds forms the backbone of the A 2D translational research and training concept. Therefore, this RTG introduces tandems of trainees with a background in natural science and medicine (Dr. med. candidates or clinician scientists) in each of the research laboratories. The formation of these research tandems, which are going to embrace the idea of translational research, will generate a close exchange of disciplines, and will allow to join forces to generate added value by learning from each other and will provide long-term benefit for the trainees and the projects. The PIs have designed all projects in a way that fosters collaboration between trainees from complementary backgrounds, and thus, the program will establish a unique platform for training and peer learning.
