The main focus of my research is reaching the ultimate limits of algorithmic techniques for solving hard computational problems. I am equally interested in working on problems of algorithm design and in using computational complexity to discover the fundamental limitations of efficient algorithms. A large part of my work uses the framework of parameterized complexity to obtain a more fine-grained understanding of problem complexity. I have worked on a wide range of combinatorial problems coming from algorithmic graph theory, combinatorial optimization, constraint satisfaction problems (CSP), and other areas.
