Current Activities

At the moment I am a research assistant at the Chair of Computer Engineering at the University of Passau under Prof. Dr. Stefan Katzenbeisser. My research focus is IT-Security in safety critical infrastructures, especially in railway systems. In a project from the German Centre for Rail Traffic Research at the Federal Railway Authority, we are researching relevant technologies for the railway sector until 2050. These technologies are investigated for security vulnerabilities that are, as of today, not sufficiently studied or standardized. Furthermore, in a follow-up project of the "HASELNUSS" project, we are developing a pretotype of a secure Object Controller which combines Safety and Security on a single device. We are also investigating its ceritfication capability.

Research Interests

IT-Security in Railway Systems
