I am heading the chair of Cybersecurity - Identity Management where I work in the area of cryptography, information security and privacy. More specifically, I'm interested in the design of cryptographic protocols with provable security guarantees. See the publications section for recent research results.

Before joining HPI in 2020, I was a researcher in the Cryptography & Privacy group of  IBM Research – Zurich. In 2010, I completed my PhD in computer science at Darmstadt University of Technology in Germany, supervised by Marc Fischlin.

News: I am co-organizing the Future of PI workshop on challenges and perspectives of personal identification, that is co-located (virtually) with the EuroS&P'21 conference. We invite contributed talk proposals addressing secure and usable IdM for presentation at the workshop.
