I studied Applied Mathematics at the University of Twente, and obtained an MSc in 1983. My field of study was combinatorial optimization and notably graph theory. In 1988 I was awarded a Ph.D. in computer science from Leiden University, where I researched modeling operating systems (and actually built something close to the real thing). After my graduation, I spent approximately five years working for TNO research, and switched back to academic life in 1993 (Erasmus University Rotterdam), to join VU Amsterdam in 1994 as an assistant professor. I was appointed full professor in 2002, and became head of the Computer Science department in 2010 and remained so until moving to the University of Twente in 2015.
