About Me

I am a PhD candidate in Felix’s Forensic Computing Group. My research focus is centered around ARM-based devices, with a special focus on Trusted Execution Environments (TEEs).
Currently, I am interested in vulnerability discovery targeting TEE firmware using rehosting and fuzzing. Additionally, I am also engaged in digital forensics for Android smartphones.
