Research
Generally speaking, my research is on the interplay between logic and games. In particular, I am working on the application of classical game-theoretic solution concepts to infinite and stochastic multiplayer games.
Until June 2009, I was involved in the DFG Research Training Group 1298.
Extended versions of some of my papers can be found on arXiv/CoRR.
