broad area of computer and telecommunications systems, ranging
from performance modelling and efficient simulation techniques to
networking protocols and radio physics.
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 telecommuni
cation 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.

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.
