Ralf Metzler
Ralf Metzler received his doctorate from the Physics Department of the University of Ulm, Germany, in 1996. On fellowships from the Alexander von Humboldt Foundation and MINERVA, he carried out postdoctoral research at Tel Aviv University with Joseph Klafter. Ralf then moved to MIT to conduct postdoctoral work with Mehran Kardar, sponsored by a DFG Emmy Noether fellowship. In 2002 Ralf was appointed assistant professor at the Nordic Institute for Theoretical Physics (NORDITA), based at that time in Copenhagen. After a period as Canada Research Chair in Biological Physics at the University of Ottawa, he was appointed professor at the Technical University of Munich in 2007. Ralf’s scientific interests range from biological physics (gene regulation, DNA physics) to anomalous stochastic processes.
Keeping up with the noise
Faster does not mean more precise—a new view of how proteins diffuse and bind to a specific site on the DNA reassesses the role noise plays in the biochemical production line that creates biomolecules from genes. Read More »
