My work is about practical IT security. I study the security and privacy of network communication, attacks on software, and ways to make login and access systems safer. I have a strong publication record, useful industry work, and more than ten years of teaching experience with very good student feedback. I also do part-time training and consulting for companies to help them protect their IT systems.
Research
I have written more than 30 peer-reviewed papers. Fifteen of them were published in top security conferences such as USENIX Security, NDSS, ACM CCS, Security and Privacy, RAID, and Euro S&P. I also work as a program committee member and help review research papers for major conferences. My work has received two Best Paper Awards and has also been recognized in industry through talks and practical impact, including presentations at CCC and OWASP. My goal is to do research that is strong in science and useful in real life.
Teaching
In 2024, my lecture Message-Level Security won the Excellent Teaching Award as the best course in the Faculty of Computer Science at Ruhr University Bochum. In 2022, I received the 5x5000 award for creating an innovative e-learning platform. I teach practical and theory-based courses in offensive and defensive security, run seminars and labs, and supervise hands-on theses. In my courses, I combine core concepts with real attack and defense examples so students learn both the theory and the practical skills.
Hobbies
Outside research and teaching, I like to spend time in nature and stay active with sports. I regularly switch between cycling, hiking, and playing ultimate frisbee. This helps me clear my mind, keep a good balance, and stay focused in my work.
