About

I received my diploma degree in computer science with the focus on IT security from the Technical University of Darmstadt in Germany. From 2007 until 2010, I worked as a researcher at NEC Europe Network Laboratories in Heidelberg. Within this time, I worked in projects mainly dealing with wireless sensor network security. In December 2010, I joined the Security in Distributed Systems group at HAW Hamburg.
