I teach philosophy at Heinrich Heine University Düsseldorf. My core interests lie in logic and argumentation, philosophy of language, and epistemology, but I also work on philosophy of action, metaphysics, and the teaching and learning of philosophy.

Earlier, I worked at Friedrich-Schiller-Universität Jena, at Goethe-Universität Frankfurt, at Westfälische Wilhelms-Universität Münster and at Freie Universität Berlin. This is also where I received my doctorate and my master's degree, after a year as a Visiting Graduate Student at Stanford University.

I live in Düsseldorf, together with my wife, the linguist Kilu von Prince, and our son Leonhard.
