Prof. Dr. Michael Ratz



Academic Career and Research Areas

Prof. Dr. Michael Ratz (b. 1973) conducts research into theoretical particle physics and cosmology. The areas he is interested in include unified theories in four and more dimensions, supersymmetry, dark matter and neutrinos.

After completing his diploma (1999) and doctorate (2002) at TUM, Prof. Ratz worked as a postdoctoral researcher at the DESY research center (2002-04) and the University of Bonn (2004-06). In 2006, he accepted the position of associate professor at TUM.
