Marco Holz M.Sc.

Former Doctoral Researcher


I was a doctoral researcher (2020/01 – 2020/10) and member of the Cryptography and Privacy Engineering Group (ENCRYPTO) at the Department of Computer Science of Technische Universität Darmstadt, Germany.

My research focuses on the design and evaluation of efficient, scalable, and secure protocols for privacy-preserving online services that leak no personal data to the service providers.
