I am a security researcher focusing 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. This interest has extended to object-capability systems and developing new confidential computing solutions. More recently, I also worked on the intersection of those topics with human-centered studies, authentication, and data science.

Since December 2021 I am a tenured faculty at the CISPA Helmholtz Center for Information Security in Saarbrücken, Germany, and heading the Trusted Systems Group. Between July 2018 and December 2021 I headed the same group at CISPA as tenure-track faculty and between June 2016 and July 2018 as a Research Group Leader.

I earned my Dr.-Ing. from Saarland University in 2016 with my thesis on ‘Establishing Mandatory Access Control on Android OS,’ which I wrote under supervision of Prof. Michael Backes. I finished my Master of Science in Engineering, Security and Mobile Computing on the KTH/DTU track of the NordSecMob Erasmus Mundus programme with my thesis “Using TCG/DRTM for application-specific credential storage and usage” in cooperation with Nokia Research Center, Helsinki, Finland.
