I have moved to the University of Amsterdam per July 1, 2007, where I will be working on security and privacy issues in, in particular, Grid systems. Please see my homepage there for recent information.
My research interests are in mobile code / mobile agent systems, distributed systems, operating systems, and security. My current work is on the Mansion mobile agent system, a new system based on a paradigm for structuring and deploying large-scale and secure mobile agent systems using the notion of hyperlinked rooms. I intend to write a dissertation about this system.
As part of the Mansion project, we implemented a jailing system to confine untrusted code. If you want to use this system, please send me an email so that we can provide you with the source code. It currently only runs on 32 bit Linux, but we are looking for volunteers who want to port the system to 64 bit Linux, and possibly other UNIX platforms.
In a previous life, I supervised the operating systems practical work course. The course now features new assignments. Descriptions of older and more recent assignments can be found on bs-old and bs-new. The current assignments can be found via the bs web page.
