Otmar D. Wiestler (born 6 November 1956 in Freiburg im Breisgau) is a German physician, a professor at the University of Heidelberg and president of the Helmholtz Association. He is not a typical basic scientist, but he successfully entered a number of highly popular fields of clinical research, including cancer research, tumor genetics and, more recently, stem cell research. He focuses on technology transfer of already existing technologies from basic science into clinical use, rather than developing the basic science. Source: Wikipedia (en)
