I'm an associate professor (Dutch: "Universitair Hoofddocent"), working in a rather broad area of computer and telecommunications systems, ranging from performance modelling and efficient simulation techniques to networking protocols and radio physics.


My research field is quite broad in the area of computer and telecommunications systems.
One main topic (also the topic of my own PhD thesis) is efficient simulation of rare events, motivated by the need to estimate small probabilities (of undesirable events such as packet loss and call blocking) in queueing models of telecommunication systems. Techniques from rare-event simulation also have broader applications.
On a broader scale, I'm interested in many aspects of communication systems and networks, in particular their mathematical aspects, such as performance and correctness.
Furthermore, I have an active interest in many aspects of radio, such as software-defined radio technology and propagation phenomena.

Research profiles

Most of my education relates to computer networking. 
I'm the coordinator and lead lecturer of the module Network Systems, a mandatory module for all computer science students and an elective for electrical engineering.
I also chair the examination board for the technical computer science and internet science and technology programs.

Courses academic year 2023/2024

Courses in the current academic year are added at the moment they are finalised in the Osiris system. Therefore it is possible that the list is not yet complete for the whole academic year.
