Born in Arnhem in the Netherlands, I studied at the University of Utrecht. There I completed basic courses (propedeuse) in law and a PhD in computer science, while developing, manufacturing, and selling board games as one of the partner-founders of Splotter Spellen. After that I briefly worked as a post-doctoral researcher at the Karlsuhe Institute of Technology and at Aarhus University in Denmark, where I designed and implemented robust and efficient algorithms for massive geographic data. From 2005 until 2018 I worked as a lecturer and researcher at the Eindhoven University of Technology in the Netherlands. In the summer of 2018 I moved to Bonn with my wife and our children Emma (2011) and Frida (2015).

Through the years I have been teaching and organizing several courses, seminars, lab projects and research projects on algorithms, ranging from the basics to advanced topics such as external-memory algorithms, computations on terrain models, clustering, and route planning. I have supervised PhD students' and Master students' projects on various topics in space-filling curves, external-memory algorithms, GPU algorithms, automated cartography, computations on terrain models, computer vision (for cars), speech recognition, geometric combinatorial optimization, spatial index structures, and more.
