Fabian Schmid
Dipl.-Ing. BScCryptology & Privacy, PhD Candidate
Fabian Schmid is a Ph.D. candidate with a research focus on cryptography and privacy. He started working for the Institute of Applied Information Processing and Communications (IAIK) while doing his bachelor's and master's degrees in information and computer engineering at TU Graz. His main research interests lie in privacy-enhancing technologies (HE, MPC, ZK), focusing on multi-key HE, verifiable computation, and real-world use cases of privacy. Fabian is advised by Prof. Christian Rechberger.
