Progress in data science, life science and technical disciplines places great demands on physicians and researchers, who must rapidly implement the latest finding from these disciplines into benefits for patients. Especially in oncology, interdisciplinary collaboration between scientist and clinical physicians is urgently needed. With the resources of the West German Cancer Center (Westdeutsches Tumorzentrum, WTZ), which is one of the leading cancer centers in Germany, the Medical Faculty will establish an Else Kröner School for Medical Scientists, which will focus on the application-oriented education of young researchers. The fellows will work closely with researching physicians from the Clinician Scientist program, which already exists at the site. Our research program is focused on the discovery of new markers for tumor diseases and the identification of new therapeutic approaches. The projects can assess patient data and bio-samples from clinical departments and the WTZ. At the interface between natural science and medicine, they take advantage of the synergies with other local structures, which already promote young scientists.
