I am a professor of philosophy of science at the Faculty
of Philosophy of the University of Groningen in the
My research revolves around probability theory and
scientific method. Topics of specific interest are
statistical inference, inductive logic, formal and
social epistemology, and causal and probabilistic
modelling. I have an interest in general philosophy of
science, but most of my work work relates to
methodological problems in specific sciences, in
particular psychiatry. I collaborate with a wide
variety of disciplines in the humanities and the
exact, social and medical sciences, and I provide
advice on uncertain reasoning and social deliberation
in judicial and policy contexts.
Some recent and newsworthy facts:
- In February of this year I started a Vici-project
entitled "Gold Rush in the Data Mine", on the use of
data science methods in psychopathology and beyond. A
project page is in the making.
- Stefan Sleeuw defended his PhD thesis on March
1st. We held a wonderful workshop in honour
of his defense.

I studied at Utrecht University, where I graduated cum
laude in both physics and philosophy. After that I
worked as a financial consultant for two years. From
2000 to 2004 I worked on a doctorate in philosophy at
the University of Groningen, for which I graduated cum
laude in 2005. The first two years after that I
lectured in philosophy of science and statistics at
the Psychology Department of the University of
Amsterdam. Until 2009 I carried out a research project
on the intersection of cognitive psychology and
philosophy of science in the University of Groningen.
Between 2011 and 2016 I worked on a research project
concerning single-case chance and statistics,
alongside a role as lecturer and head of department.
From 2020 until 2022 I served as dean of the Faculty
of Philosophy. More information can be found in my CV and in my list
of publications, presentations, and outreach.
