I am a professor for Theoretical Philosophy at the University of Frankfurt

 Before coming to Frankfurt, I've been a junior professor at the University of Stuttgart and at the University of Tübingen, a postdoctoral researcher at DebateLab at the Karlsruhe Institute of Technology, and an assistant professor at the University of Konstanz. My main research interests are the philosophy of logic and epistemology. Currently, I am mainly working on the rational profile and decision theoretic relevance of suspension of judgment as PI of the project “Doxastic Suspension. Its Nature, History, and Logic.”
