I’m an assistant professor (wissenschaftlicher Mitarbeiter) for theoretical philosophy at the University of Bielefeld.

My research revolves around descriptive as well as normative aspects of language. In virtue of what do words have the meanings they do? Would it sometimes be better if they had different meanings? If so, what, if anything, can we do to change their meanings? In approaching these questions, I employ a broad range of methods, ranging from typical philosophical argumentation, the vignette-based methods of experimental philosophy, to consultation of empirical research from neighboring disciplines in cognitive science. One reason why the above questions about language are so interesting is that they are tightly interwoven with questions about philosophy itself. To what extent should philosophers take responsibility for their use of language? Should they try to actively assess and improve the meanings expressed by the terms of ordinary language? Is that perhaps even the central contribution that society should expect from philosophers? These questions date back to the very beginnings of analytic philosophy, and they have regained spotlight in recent work on conceptual engineering, conceptual ethics, and ameliorative projects.

I am a member of EXTRA, of the Forum für Streitkultur, of the GAP and the Aristotelian Society. I edit the category ‘conceptual engineering‘ on philpapers. I am on philpeople, on googlescholar and on facebook. You find my University website here.


My article “Conceptual Engineering. Begriffe auf dem Prüfstand” just appeared here (open access).

My article “Chalmers on virtual reality: Realism on the cheap?” was just accepted by Analysis.


I got a BA and and an MA from Humboldt-University Berlin and an MLitt from St Andrews / Stirling. During that time, I received a scholarship from Studienstiftung des Deutschen Volkes. As a Phd student, I spent time at the University of Cologne and at ConceptLab at the University of Oslo. My PhD supervisors were Joachim Horvath and Thomas Grundmann.
