I am currently doing a postdoc at Microsoft Research Cambridge in the Programming Principles and Tools group. I am a member of the Security sub group.
Before that, I did my PhD at COSIC (Computer Security and Industrial Cryptography) group at the Department of Electrical Engineering ESAT of the K.U.Leuven.
In September 2004 I started to work as a researcher in the European PRIME project (Privacy Enhancing Identity Management for Everyone), first in Frankfurt in the group on mobile business at the Johann Wolfgang Goethe University and then as a PhD student at COSIC. After the end of the projet I continued to work for some time on the follow up project PrimeLife.
Even earlier, I received the degree of Master in Computer Science (Diplom Ingenieur, Dipl.-Ing.) from the University of Klagenfurt, Austria and visited IBM Research Zurich for half a year to do my master thesis.
I am currently collaborating with the following colleagues on privacy-friendly smart metering and formal verification of cryptographic protocols.
