PhD Thesis
On August 31, 2009 I obtained my PhD degree at the Eindhoven University of Technology, for my thesis Partial Fields in Matroid Theory. As is customary in the Netherlands, I have made a number of printed and bound copies of my thesis. If you are interested I am happy to send you one of these. You can also read the text online, and I have compiled a list of errata.
Technical Reports, Master Thesis, Proceedings
Most conferences I attended have no proceedings. See my talks page for slides and posters.
