About me

I am a philosopher of science and conceptual theoretical biologist working on conceptual questions in and about the life sciences. Officially I am Professor of Philosophy of Science and Technology at Leibniz Universität Hannover in Germany. For more on my current positions 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 I 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.
