I am Professor of Practical Philosophy at Bielefeld University and Principal Investigator of the ERC project "The Structure of Normativity". My research focuses on foundational questions in moral philosophy, metaethics, and the theory of reasons and rationality. I also work on issues in  normative and applied ethics, political philosophy and epistemology.


I studied philosophy, early modern and modern German literature, and cultural studies at the Humboldt University of Berlin (M.A. 2007), where I also received my doctorate in philosophy (2014). My dissertation examined the normativity of rationality (published 2017 by Oxford University Press, awarded with the Humboldt Prize 2014 and the Stegmüller Prize 2018). I was a visiting student at the University of Nottingham (2003-2004), as well as a visiting scholar at the University of California, Berkeley (2009-2010) and the Torcuato Di Tella University in Buenos Aires (2011). I worked as a lecturer and research assistant at the HU Berlin (2009-15), as a research associate at the Australian National University in Canberra (2014), as a visiting professor at the University of Hamburg (2016-17), as a postdoctoral researcher at the Technical University Dresden (2020-21), and as a research fellow of the Centre for Advanced Studies in the Humanities "Human Abilities" at the FU and the HU Berlin (2021-22). In 2022, I received an ERC Starting Grant for my research project "The Structure of Normativity", which will run for five years. I joined the philosophy department at Bielefeld University in March 2023.
