Interim Professor for Theoretical Computer Science
My research aims to develop new algorithmic approaches for computationally hard problems. In particular I am interested in algorithms for global NP-hard optimization problems such as the traveling salesperson problem or the Steiner tree problem. I am particularly interested in using and developing techniques from combinatorial optimization, with a special focus on linear programming and related advanced methods.
As a second major theme of my research, I focus on online problems. The purpose of online computation is to analyze strategies to take decisions in the absence of future information. Unlike in the case of NP-hard optimization problems, the hardness of online problems does not arise from limited time resources but instead from a limited knowledge of future events. My research on online algorithms aims to identify the inherent properties of online problems that are responsible for the existence or nonexistence of useful algorithms.
