Embedded Systems Security

I am interested in evaluating the security of embedded systems and IoT devices. Mainly I investigated car ECUs, smart home and smart grid devices. Some areas I looked into are: DAB/FM signals, 2G/3G mobile communications, WiFi Co-processor fuzzing, binary analysis and protocol reverse engineering.


Currently I am focused on cryptography topics, such as the performance, security and efficient software implementation of lightweight ciphers on embedded systems and key management in critical IoT networks.


In my free time, I play Tennis at DJK Neumarkt and also manage the Tennis branch of the Club. Moreover, I (try to) play Golf and old Blues/Rock stuff on guitar.


Before entering university, I completed an apprenticeship as IT-specialist ("Fachinformatiker"). I received a BSc in Automotive Computer Science from THI. During my bachelor studies I was enrolled in BMW's SpeedUp program, which allowed me to spent lots of time at BMW's IT security (research) department as an intern. I also lived in Guadalajara (Mexico), where I studied at Technologico de Monterrey for a winter term. I received a MSc from OTH Regensburg in Technical Computer Science and Embedded Systems Security. Since November 2018 I am a PhD student at the Laboratory for Safe and Secure Systems (LaS³) of OTHR.

I served as a PC member or chaired a session on the following conferences:

  • Embedded World Conference, Februrary 25-27, 2020, Nürnberg, Germany
  • ACM/SIGAPP Symposium On Applied Computing (ACM SAC 2020), March 30-April 3, 2020, Brno, Czech Republic (online)
  • ACM Computer Science in Cars Symposium (ACM CSCS 2018), September 13-14, 2018, Munich, Germany


I'm am always looking for motivated students in the area of embedded software development, cryptography and security. If you want to write a project assignment, bachelor/master thesis or work in one of these areas, don't hesitate to contact me via mail. My S/MIME certificate can be found here.
