For more than three decades, I mainly deal with the exact and approximate solution of different types of scheduling problems beginning around 1980 with the development of genetic algorithms for the flow shop scheduling problem. I also deal with complexity issues, scheduling problems under uncertainty, train scheduling problems and various graph-theoretic problems. I was involved into several research projects supported by German Research Society (DFG), European Community (INTAS) and Belarusian Republican Foundation of Fundamantal Research. I am an associate editor of International Journal of Production Research, of Journal of Scheduling, and of Operations Research and Decisions. I am also a member of the Editorial/Advisory Board of 14 further journals. I was a guest editor of special issues in six international journals and a member of the program committee of more than 55 international conferences.
