Personal:
My name is Tim Kehl and I am a researcher at the chair of Prof. Dr. Hans-Peter Lenhof. We are developing new algorithms, tools and databases for the analysis of human pathologies, especially cancer. In particular, I am interested in the analysis of deregulated biological processes and the identification of molecular factors that drive those processes.
