Research vacancies

I have an operning for a postdoc to work on advanced inter-domain routing concepts. Please check the job description for more details. The closing date is Feb 19, 2024.

I also have an opportunity for an M.Sc. student to do their final project on the concept of a "Trusted Topology", which the IETF's RATS Working Group is developing. The work involves protoyping a Trusted Topology and designing and evaluating routing mechanisms that use it to provide "high trust" data paths across Autonomous Systems. The project is part of the TUCCR research institute.

Courses: Advanced Networking and IoT Security

I coordinate and teach two M.Sc. courses at the University of Twente (UT): Security Services for the IoT (SSI) and Advanced Networking (ANET), both of which are collaborations with SIDN Labs. SSI is also part of the 4TU cybersecurity Master program.

ANET is a 1st quartile course (September through November), whereas SSI is part of the UT's 4th quartile teaching program (April through June).

If you're a student and intereseted in SSI or ANET, then please make sure to browse a few of the courses' papers before you sign up to verify that the course matches your interests, study plan, prerequisites, etc. You can sign up through the UT's course management system, OSIRIS. Hope to see you in class!

The ANET teaching team consists of Pieter-Tjerk de Boer (UT), Geert Heijenk (UT), Roland van Rijswijk-Deij (UT and NLnet Labs), and myself. The SSI teaching team conists of Antonia Affinito (UT), Ting-Han Chen (UT), Etienne Khan (UT), and me. Former SSI team members are Elmer Lastdrager (SIDN Labs) and Ramin Yazdani.

M.Sc. Projects

I occasionally mentor M.Sc. students, although unfortunatly I can only handle one at a time. If you're interested in an M.Sc. project on the DNS, the Internet's routing system, or time services, then feel free to drop me an email.

In the past, I (co-)advised these students:
