Short Description of Professional Activities

I received my M.Sc. in psychology/artificial intelligence from Leiden University in 1993. From 1994 till 1999 I worked as a researcher at Maastricht University, department of Computer Science and the department of Communications Research & Semiotics. My research area was Multi-Agent Systems, and involved two distinct areas, viz., Agent Technology and Adaptive Agent Design.

From 2000 till 2003 I was assistant professor in Artificial Intelligence at the Vrije Universiteit. My main research and educational activities were in the area of Self-Organizing Systems.

From 2004 till 2011 I worked as a researcher at the UvA in the System and Network Engineering Group, in the areas of Optical Networking, Network Protocol Performance, Network Resource Scheduling and Optimization, and Authentication Authorization and Accounting (AAA).

Our group has actively participated in several EU IST projects and continues to do so. One of the projects I have been involved in is NextGRID in which standards and architectures for the next generation GRID were developed. As part of the overall NextGRID architecture I designed and developed a AAA toolkit, building on previous work done in our group. The software and documentation can be downloaded here (gzipped tar file) and the final report describing scheduling optimization and intrusion detection components that were added in the final phase can be found here.

The EU funded Phosphorus project had the objective to create an infrastructure that allows to set up multi-domain circuits (point-to-point connections) in various European research networks controlled by different control-planes such as ARGON, ARGIA (UCLP), IDC and OpenDRAC. The unified request interface with which multi-domain (reservation) requests can be made is called the Harmony Network Service Plane. My main contribution was the development of a translator able to transform requests between the Internet2 IDC and the Harmony NSP to enable multi-domain path reservations among all the Phosphorus networks (Europe) and de Internet2 network (United States).

In the GigaPort project (funded by SURFnet) my focus was on the development of an experimental network at the UvA itself and the integration of it with NRENs participating in the GLIF community. The main achievement was developing a component for the IDC that can set up paths through the experimental network at reservation activation time, while the network equipment is a mixture of VLAN capable switches (IEEE 802.1Q) and PBT capable switches (IEEE 802.1Qay).
