I'm working for European Microsoft Innovation Center (EMIC) in Aachen. Germany. At EMIC, I'm working on security research projects with a strong focus on web services and federation concepts.
Before joining Microsoft in mid-2003, I worked at Siegen University and started the Apache XML Security project (http://xml.apache.org/security/).
