Ulrich Derigs received his Master degree (Diplom) in Mathematics in 1975, his Ph.D. degree (Dr.rer.nat) in Mathematics in 1978 and his Ph.D. degree (Dr.rer.pol.) in Economics and Business Administration in 1981 from the University of Cologne. In 1985 he got his Habilitation in Operations Research from the University Bonn.

From 1976 until 1980 Ulrich Derigs joined the University of Cologne as an assistant professor first at the Mathematical Institute with Prof. R. E. Burkard and later at the Institute for Industrial Engineering with Prof. Th. Ellinger. In 1981 he became a member of the Sonderforschungsbereich 21 (DFG) "Ökonomische Prognose-, Entscheidungs- und Gleichgewichtsmodelle" and an assistant professor at the Institute for Econometrics and Operations Research at the University Bonn with Prof. B. Korte.

In 1985 he became the chairman of the newly founded Lehrstuhl für Betriebsinformatik and Operations Research at the University of Bayreuth, in 1990 he was appointed the chairman of the newly founded Seminar für Wirtschaftsinformatik and Operations Research at the University of Cologne.

Ulrich Derigs is a member of the Gesellschaft für Operations Research (GOR), INFORMS, ACM, and IEEE. From 1988 until 1992 he was the Editor of OR-Spektrum, presently he is the Associate Editor for several other journals. From 1993-1996 he was a member of the board of directors (Vorstand) of DGOR. In 1997 he was president of DGOR and 1998 president of GOR, the German Operations Research Society, which is the merger of DGOR and GMOEOR.

Ulrich Derigs` research interests are in the areas of network optimization, combinatorial optimization and mathematical programming with emphasis on efficient algorithms and data-structures as well as on decision and data modeling and the conception, design and implementation of OR-based decision support systems. His research was funded by the Deutsche Forschungsgemeinschaft (DFG), Deutscher Akademischer Austauschdienst (DAAD), different private companies and the government.
