Karol Nowicki-Osuch is a Junior Group Leader (equivalent of Assistant Professor in the US) and the head of Tumorigenesis and Molecular Cancer Prevention group at the German Cancer Research Center (DKFZ) in Heidelberg. Before joining DKFZ, Karol was an Associate Research Scientist at the Irving Institute for Cancer Dynamics (IICD) at Columbia University. The origins of Tumorigenesis and Molecular Cancer Prevention group can be traced to Karol’s time at Columbia. Prior to his move to New York City, Karol was a Postdoctoral Research Associate in Prof. Rebecca Fitzgerald's laboratory at the University of Cambridge, UK. Karol’s experience and interests lie at the interface between wet- and dry-lab cancer biology research. Over recent years, his work has been focused on questions associated with the early stages of oesophageal cancer development including the transition from normal to cancer tissues. As the head of the Tumorigenesis and Molecular Cancer Prevention group, Karol focuses on spearheading the development of experimental and computational methods for the analysis of solid tumors in three dimensions in partnership with the New York Genome Center, IICD and the University of Cambridge.
