2019: Busy Beaver Award "Selected Topics in Mobile Security", Universität des Saarlandes
I am security researcher with focus on (mobile) operating system security and trusted computing. In the past, I was particularly looking into mandatory access control systems for the Android OS and integrating hardware security building blocks into mobile operating systems.
Since May 2016 I am employed as the research group leader of the Trusted Systems Group at the CISPA Helmholtz Center for Information Security in Saarbrücken, Germany.
