My research interests lie mainly in graph theory. I started my investigations by working on domination-type problems when I was doing my MSc. Then I concentrated on problems which are hard to solve on general graphs. Discovering structural properties of graph classes and exploiting them to cope with hard algorithmic and combinatorial problems formed the base of my PhD research. I am interested in all kinds of graph theory problems and I am always open for new ideas. Currently, my research interests focus on the areas mentioned below.
