About me

I am the head of the Artificial Intelligence Group at the Faculty of Mathematics and Computer Science of the FernUniversität in Hagen, Germany. I received my PhD degree from the university of Dortmund (Germany) in 2011 and my habilitation degree from the university of Koblenz-Landau (Germany) in 2016. My research focus is on formal methods of knowledge representation and artificial intelligence, both from a conceptual as well as algorithmic perspective. I am interested in formal models of argumentation, in particular with respect to algorithmic approaches, quantitative extensions, game theoretical aspects for application in multi-agent systems, the relationship of argumentation and belief revision, and inconsistency measurement. Further interests include probabilistic reasoning with incomplete and inconsistent information in propositional and first-order representations of knowledge.
