Research interests

Computer science

Currently I'm not really doing any research, because all my time is spent on teaching. But before this I did research in the computer science department, more specifically within the Digital Security groups on topics like smart cards, the electronic passport and voting systems.

Mathematics

Before I worked for computer science, I worked at the mathematics department.

Algebra, Computer algebra, Polynomial maps. Under supervision of Arno van den Essen I wrote my PhD. thesis Nilpotent Jacobians.
Differential and Difference Equations and Computer Algebra, a conference in honour of A.H.M. Levelt's 65th birthday. I was the technical editor of the proceedings.
The Meisters Conference. A conference on polynomial maps and the Jacobian Conjecture. A conference in honour of the mathematical work of Gary Meisters. I was the technical editor of the proceedings.
