About me

I am a philosopher of science and conceptual theoretical biologist, which means that I work on conceptual questions in and about the (mainly life) sciences. This is philosophical research, as it encompasses conceptual analysis, and systematic inquiry into the epistemological and metaphysical aspects of scientific theories and practices. It is also work in theoretical science, as it does not just look at science from the outside, but participates in theory building in the sciences by clarifying theoretical problems and proposing conceptual approaches to resolving these. Accordingly, I publish my work both in philosophy journals and in science journals. For details on my current work and academic background, see my academic bio.


I am from The Hague on the Dutch North Sea coast. I was educated at Aloysius College and Leiden University, and am an alumnus of L.V.V.S. Augustinus in Leiden. I divide my time between East Lansing, Michigan, and Hannover, Germany. But: Zoo ik ièts ben, ben ik een Hagenaar.
