I am a PhD student at HSG in the cybersecurity group of professor Katerina Mitrokotsa. I am interested in a wide range of cryptographic topics and especially applications of cryptography to real world problems. Recently, I have been working on privacy preserving biometric authentication protocols and (fuzzy) password based key-exchange. Furthermore, I am interested in functional encryption and in particular its use in privacy preserving computation.

I received both my Bachelor's and Master's degree at the Karlsruhe Institute of Technology (KIT).
