Since receiving my Ph.D. in Computer Science from Aarhus University in 1993, I have held semester-long visiting professor positions at the University of Wisconsin, Madison, the University of California, Irvine, the University of Waterloo, and several times at the University of Toronto.
My primary research interest are online algorithms, data structures, database systems, and algorithms in general.
I have had the pleasure of working together with great colleagues and Ph.D. students of 18 different nationalities, resulting in around 50 journal articles, in addition to a similar number of conference publications and other contributions.
Almost all my guests, research visits, and conference participations during my career have been supported by the Independent Research Fund Denmark, Natural Sciences, as was the previous project, Algorithmic Challenges, of which I was the PI, and the new project, Online Algorithms and Cheminformatics Meet Concurrency. I also participated in the recent On-Line Algorithms and Advice grant from the Villum Foundation.
Over the years, I have accepted quite a few appointments of a more service-oriented nature, such as head of department for 3½ years, and, since 2014, head of the national External Examiners in Computer Science.
