I am the chair of Combinatorial Optimization (CO) at the TU Eindhoven. All my academic degrees are from the TU Graz (Austria): I got my diploma degree under the supervision of Hermann Maurer, and my Ph.D. degree under the supervision of Franz Rendl. I received the "venia legendi" (Habilitation degree) for Discrete Mathematics and for Theoretical Computer Science. I have worked at the Free University Berlin, TU Graz, University of Twente, TU Eindhoven, and TU Berlin. Since April 2004, I am working in the Department of Mathematics and Computer Science of the TU Eindhoven, in the Combinatorial Optimization group.
