I am currently on a DFG funded research leave at the Philosophy Department of the City University of New York, but I remain affiliated with the Institut für Philosophie of the Universität Bonn. My main research interests lie in the philosophy of language, in epistemology, and in the philosophy of logic. You can find out more about my research in the works and talks section, where I uploaded some of my papers and slides. Information about my classes can be found in the teaching section. In case you wish to contact me, please send me an email.


I mostly work on logical pluralism these days. More specifically, my current research project is concerned with how logical pluralists can capture the notions of the correctness of a logic and of rivalry between logics. You can find out more about the project here. I just arrived in New York where I will be working on some aspects of the project with Graham Priest.

I am also happy to report that my first paper on this topic is forthcoming in a special issue on logical pluralism and normativiy in Inquiry. An online first version of the paper is here. Please don't hesitate to contact me, if you cannot access the journal–––I still have some free copies to give away.

Another issue I think about a lot is whether and in what sense logic may be normative. I am preparing a joint paper with Filippo Ferrari on this and we already presented some of our ideas at a couple of conferences. We will actually host a colloquium on "Logics, Norms, and Reasoning" at the next GAP conference in 2018. I will post more about this soon.

Apart from that I keep working on context-sensitivity and I am excited to be part of the newly founded research network on "The semantics and metasemantics of context-sensitive language" (also funded by the DFG). Network member Julia Zakkou already hosted a workshop on "What contexts can and cannot do" in Hamburg, last April and there is another one coming up in Berlin this November, organized by Hazel Pearson. Being in New York, I will miss this, unfortunately, but I hope to be back for the other workshops.
