Since 2003 I am full professor for Design and Analysis of Communication Systems at the University of Twente, in the faculty for Electrical Engineering, Mathematics and Computer Science (EEMCS).
My work focuses on quantitative methods and techniques to support the design of computer and communication systems, these days often addressed as cyber-physical systems. I lately also have been working on themes related to dependability of critical infrastructures and smart grids.
I was born on September 27, 1964, in Lichtenvoorde, a small town in the eastern part of the Netherlands, famous, among others, as the hometown of the Zwarte Cross. After having attended primary school in Lichtenvoorde, I attended the Scholengemeenschap Marianum(gymnasium) in Groenlo, a small city in the vicinity, the hometown of the famous Grolsch beer (the old name for Groenlo is Grol, thus explaining the name Grolsch). These days, Lichtenvoorde and Groenlo are both part of the county Oost-Gelre.
I obtained my Ph.D. in 1991 and my M.Sc in 1986, both from the University of Twente. I did my final master project, in 1986, at the University of Dortmund, Germany.

Past Positions & Roles
- In the period 2012-2015, I served on the program council of High-Tech NL, the Dutch association for innovative high-tech companies, (applied) research institutions and universities, as representative of the three technical universities in the Netherlands.
- In the period March 2009—February 2013, I have been scientific director and chairman of the Embedded Systems Institute in Eindhoven. ESI was an independent public-private open innovation applied research institute for high-tech embedded systems, employing around 35 FTE. As of January 1, 2013, ESI has been acquired by TNO.
- In 2012 I served on the program council of Point-One, the Dutch innovation program for high tech systems. As of January 1, 2013, Point-One has been transformed into High-Tech NL.
- Throughout 2011, I have been serving on an advisory committee of the Province of Overijssel to shape the Innovation Policy for the Region Twente for the next 5 years.
- Board member of the Dutch computer science research school ASCI (Advanced School on Computing and Imaging), November 2005 – November 2015.
- Chairman of the Supervisory Board of Breedned (2009-2011).
- Head of the Department of Computer Science and Member of the management team of the EEMCS faculty at the University of Twente (August 2008-February 2009).
- Member the management team of 3TU.NIRICT, the National Institute for Research on ICT (August 2008-February 2009).
- Co-leading the 3TU Centre of Excellence on Dependable ICT Systems (CeDICT) as part of NIRICT (2005-2009).
- Professor (C3) for Distributed Systems in the Department of Computer Science at the Rheinisch-Westfälische Technische Hochschule (RWTH) in Aachen, Germany (October 1995-December 2002).
- Lecturer at the University of Twente, in the Department of Computer Science (January 1990 through September 1995).
- Visiting scientist in the Teletraffic Research Centre at the University of Adelaide in Australia (spring 1993).
My personal research focuses on model-driven design of embedded computer-communication systems and the evaluation of their performance and dependability. Since 2000, I have also been working on stochastic model checking techniques. During my term as director of ESI, I have become interested in system design and engineering as a discipline, especially in relation to industrial applicability (now also addressed under the name of ‘smart industry’). Lately, I also focus more on energy systems, such as smart grids, and critical infrastructures. Due to my new role as chairman of Commit2Data, I am also working more towards big data and its applications.
In the cause of my career, I have guided numerous master students through their final project, and have had the honor of acting more than 25 times as PhD advisor (“promotor”).
I wrote a textbook on Performance Evaluation of Computer-Communication Systems (Wiley, 1998), and published 6+ conference proceedings (with IEEE and Springer) and did put together multi-author books on performability (Wiley, 2001) and on validation of stochastic systems (Springer, 2003). I published 150+ papers in journals and at (full-review) conferences; see DLDB, Google scholar, or the research.utwente database.
I have been member of well over 100 international program committee of conferences in my field, acted as chairman of a number of international conferences (TOOLS 2001, PNPM 2001, MMB 2001, QEST 2004, DSN/PDS 2005, PDMC 2006, PDMC 2007, QEST 2015), and have edited more than 10 special issues for various journals.
