I'm a


I'm an IT security professional with a Ph.D. in computer science and a solid background in economics with a strong ability to lead, coach, and develop teams. I currently work as the Senior Information Security Officer at Taurus SA in Geneva. Before this, I served as a security researcher at the IT Security Infrastructures Lab at Friedrich-Alexander University in Erlangen-Nuremberg, and as the Chief Information Security Officer at Deutsche Bahn Connect GmbH. Additionally, I currently give lectures on mobile application security and an introduction to cybersecurity at the Baden-Wuerttemberg Cooperative State University (DHBW) in Mannheim. I am most passionate about information security and its ever-evolving threat landscape, which in my opinion is one of the biggest challenges companies face nowadays. Over the past years, I have worked with many key technologies, namely IoT, mobile, and serverless computing, specializing in security assessments and information security audits, to help companies and organizations address their unique threat landscapes. My deep dives into these technologies and several security frameworks resulted in a vast knowledge pool and project experience in IT security-related topics and the ability to communicate core concepts to most target groups due to my startup and public speaking experience.
