About me
I am a researcher at KIT since 2020. My research is centered around confidentiality analysis for software architectures with a special focus on uncertainty at design time. I am involved in FluidTrust and KASTEL-ESS, where I investigate continous software analysis and its application to mobility systems. I am also involved in the Team Project Software Development (TES) and advise students' theses as well as seminar and practical course topics and I am maintainer of the JPlag plagiarism detector. Besides my university activities, I have more than a decade of experience in video production and one of Germany's largest social media presence in tech education and computer science. If you're looking for a thesis, a seminar or practical course topic or a paid position as student assistant, just visit the Open topics!
