I am a professor and Rosalind Franklin fellow at the Department of Theoretical Philosophy of the Faculty of Philosophy of the University of Groningen. I am also an external member of the Munich Center for Mathematical Philosophy, and one of the Editors-in-Chief of Synthese. In July 2018 I'll be moving to the Department of Philosophy of the Free University (VU) in Amsterdam.

My main fields of research are history and philosophy of logic, philosophy of mathematics, and social epistemology. I also have general interests in medieval philosophy, philosophy of psychology and cognitive science, general philosophy of science, philosophy of mind, issues pertaining to gender and race, and empirically-informed approaches to philosophy in general.

From 2011 to 2016 I led the NWO-funded research project 'The Roots of Deduction'. From 2018 to 2023 I will be leading the ERC-funded project 'Social Epistemology of Argumentation'.

I used to blog at New APPS and M-Phi.
