Research Interests

I like getting to the core of things. More specifically, I am interested in the complexity of discrete processes and the reasons behind their complexity. Currently, my main focus is on the analysis of randomized processes. However, I am also interested in complexity theory and game theory, where complexity seems to emerge from simple concepts. For all of these settings, I am not only interested in the complexity alone but also in the analysis and development of methods and tools used in order to derive good run time results.
