Prof. Dr. Silke Rolles


Mathematical physics



Academic Career and Research Areas

Professor Rolles (b. 1972) carries out research in the field of probability theory. She is especially interested in processes in random media, interactive particle systems and statistical mechanics.

After studying mathematics at Saarland University, she conducted research at EURANDOM in Eindhoven (Netherlands) and received her doctorate in 2002 at the University of Amsterdam. She acquired her postdoctoral teaching qualification (habilitation) in Bielefeld in 2005. Her scientific career has taken her to the University of California in Los Angeles, the Technical University of Eindhoven and the University of Zurich.
