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.
Here is my CV.
My main fields of research are history and philosophy of logic. I also have general interests in medieval philosophy, philosophy of psychology and cognitive science, philosophy of mathematics, general philosophy of science, philosophy of mind, and empirically-informed approaches to philosophy in general.
I am now (2011-2016) leading the research project The Roots of Deduction.
