PhD

Open doctoral topics

Our department continuously offers doctoral projects for students of human medicine and dentistry. Current doctoral topics can be found on the Eportal. We also offer doctoral positions for graduates in the natural sciences - especially physics - and for engineers in the fields of biomedical engineering and optical metrology. In this way, we enable interdisciplinary research at the interface of medicine, physics and technology.
