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 occasionally consult the people at Campus Asyl regarding IT issues. I also try to play 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'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.
