Biography/History:

Claudia Tanja Mierke is a full professor at the Peter Debye Institute for Soft Matter Physics and Head of the Department of Biological Physics at the University of Leipzig. Her main areas of research have included the interaction of cancer cells and endothelial cells; effects of external mechanical stimulation of cancer cells on gene expression and tissue invasiveness on different mechanical and structural environments; the investigation of the dynamic interplay between the cells and their microenvironment from a biophysical point of view.
