Hi! I'm a Jump.Start postdoc at the CASA Excellence Cluster at Ruhr University Bochum in Germany. Before that, I was a visiting researcher at the Emerging Wireless Technologies (WiTech) lab at Carnegie Mellon University in Pittsburgh. I did my PhD at the Max Planck Institute for Security and Privacy (MPI-SP), supervised by Prof. Christof Paar, graduating summa cum laude with the dissertation "Physical-Layer Security in Future Wireless Systems".
Wireless communication is the foundation of today's digital societies, with digital information routinely protected by cryptography. Emerging wireless systems such as 6G, however, sense the physical environment and place radio propagation under software control, acquiring and acting on physical information for which no comparable security primitives exist. I study radio propagation as an adversarial medium that attackers can measure, manipulate, and weaponize, but that can equally serve as a defensive asset. My goal is to establish the physical layer as a foundation for trustworthy sensing, communication, and hardware integrity.
My research spans three lines: (i) the security of smart radio environments built on reconfigurable intelligent surfaces (RIS, also known as metasurfaces), (ii) the security and privacy implications of wireless sensing, and (iii) physical-layer security for computing systems. I investigate both attacks (e.g., RIS-based jamming, relay and distance manipulation) and defenses (e.g., Anti-Tamper Radio, IRShield), taking an experimental approach: I design, build, and evaluate prototype systems in real-world settings across technologies such as Wi-Fi, UWB, Bluetooth, cellular systems, mmWave radar, and RIS. My work has appeared at leading security venues, including IEEE S&P, ACM CCS, and NDSS.
