I am an Assistant Professor of Philosophy at CONCEPT, University of Cologne. Before that I was an Alexander von Humboldt Fellow at the Munich Center for Mathematical Philosophy. My area of specialization is epistemology.

Currently my research focuses mostly on (a) the epistemology of reasoning, and (b) the nature and normativity of suspended judgment. When it comes to (a), I argue that how good a process of reasoning is depends partly on the set of possibilities that the reasoner intends or means to quantify over. This gives rise to a unified account of good (theoretical) reasoning: good reasoning is reasoning that preserves truth in its designated set of possibilities. I also defend the view that reasoning is a source of knowledge in its own right, as opposed to just a means of transmitting knowledge from premise-beliefs to conclusion-beliefs. I have always been amazed by the fact that one can make discoveries through sheer reasoning, without dipping one's toes in the waters of empirical evidence.

When it comes to (b), I argue that rational suspended judgment is governed by norms/requirements that are very similar to the ones that govern rational belief (e.g., sometimes suspending judgment about one thing requires one to suspend judgment about other things). Rational requirements for suspended judgment can then be used to assess various forms of agnosticism/skepticism, both in philosophy and elsewhere. 

I am also interested in philosophical logic and the theoretical foundations of cognitive science/AI. Besides being an academic, I skateboard and from time to time I compose electronic songs.
