Research Fellow, OpenKRITIS (Insignals GmbH)

I am a PhD student at Hasso Plattner Institute supervised by Jiska Classen at the chair of Mobile and Wireless Security. The goal of my research is to democratize knowledge about mobile information systems and improve their security. My work is supported by NLnet through the Horizon Europe funding program. I am especially interested in the behavior of proprietary wireless interfaces and interfaces inside operating systems.

Besides my role as Research Assistant at the Hasso Plattner Institute, I am a publisher at OpenKRITIS where my work engages with regulators, industry, and academia across Europe.
