I am no longer working at the Institut for Algebra and Geometry and moved to the Programming Paradigms Group. Since this page is no longer maintained, please have a look at my new homepage.

Interests

Within my work at the Institute for Algebra and Geometry I was interested in group theory, in particular the coset graphs of certain subgroups and their graphtheoretical properties.

Besides that I am interested in functional programming (e.g. Haskell) and the corresponding type theory, in formal verification and theorem proving (e.g. Isabelle) and Free Software in general. More about these topics can be found on my meinem Weblog.
