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

Before joining the HPI in 2020, I was a researcher in the Security & Privacy group of IBM Research – Zurich. In 2010, I obtained my PhD in the cryptography group of Marc Fischlin at the Darmstadt University of Technology in Germany, which followed a Diploma in computer science from Dresden University of Technology.

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.
