I studied Wirtschaftsmathematik (mathematics and business administration) at the Universität Augsburg. From June 1991 to February 1998 I have been a research and teaching assistant at the Institut für Informatik of the Universität zu Köln and working in the group of Prof. Dr. Michael Jünger. Here, I finished my Ph.D. (Dr. rer. nat) in 1995.

Since March 1998 I am working at sd&m in München.
