My picturE

Hans van den Berg received the M.Sc. and Ph.D. degree in mathematics (stochastic operations research) from the University of Utrecht, the Netherlands, in 1986 and 1990 respectively. From 1986, he worked at the Centre for Mathematics and Computer Science (CWI), Amsterdam. In 1990, he joined KPN Research (TNO Information and Communication Technology, since January 2003). He is particularly working on performance analysis, traffic management and QoS provisioning for wired and wireless multi-service communication networks (ATM, IP, UMTS/HSDPA, WLAN, ad-hoc networks). In these fields, he has co-operated within many national and European research projects. He is currently active as Management Committee member in the European COST Actions COST 290 and COST IC0703, and as Coordinator of the European FP7 project SOCRATES.

Currently Hans van den Berg is a Senior Research Fellow within TNO ICT and has a part time professorship “Traffic engineering in mobile and ad hoc networks” within the group Design and Analysis of Communication System of the Faculty of Electrical Engineering, Mathematics and Computer Science of the University of Twente, The Netherlands. He is co-founder of the national expertise centre "E-Quality", a co-operation between University of Twente, TNO, CWI, TUD and TU/e.
