Academic publications


The research papers below were written at the Distributed and Embedded Systems group of the University of Twente – which is now merged in a new group called Services, Cyber security and Safety, supervised by Sandro Etalle (UT) and Prof. Pieter Hartel (UT), in collaboration with Ricardo Corin, Gabriele Lenzini, and Jerry den Hartog.

My PhD research was funded through the IOP GenCom project called “Privacy in an Ambient World”. To explain our research question, our mission: We were working on the problem of protecting the privacy of data, in the new networked world, and in particular, on the design of flexible access control mechanisms for distributed heterogeneous systems. It is hard to reconcile confidentiality and availability using conventional protection mechanisms. In settings where confidentiality is a prerequisite, a burden is placed on the users, who struggle to use the protected systems. In other settings, where availability is more important, users are inclined to bypass protection mechanisms, in order to get the work done. We propose more flexible protection mechanisms to address settings where both confidentiality and availability are important (e.g. medical environments, collaborative work environments). For more details, see for instance our article about protecting health records.

Below a list of my academic publications – most of these papers have appeared as book chapters in academic publications or as articles in journals or conference proceedings.

In 2002 I graduated in Theoretical Physics at the University of Utrecht, by defending a research thesis in Quantum Mechanics. The thesis actually goes into the details of mesoscopic quantum mechanics, why and how quantum mechanical particles lose their quantum behavior when they come into contact with many particles. The thesis focusses on spin particles moving thru a bath of other particles (also known as brownian motion). Decoherence is the main problem when building quantum computers.
