🏫 Academic life
- 2015-2022: PhD student at Paderborn University in the group of Johannes Blömer.
- Topic: anonymous credentials and applications to privacy-preserving systems.
- 2010-2015: Computer science Bachelor and Master at Paderborn University (with distinction).
📈 Projects I’ve been involved in
- I co-created 🦎 Cryptimeleon, a Java library for prototyping privacy-preserving crypto.
- I am planning and supervising the prototype implementation of our 💳 incentive system as part of a transfer project.
- I’m a contributor to the ZKProof 🗄 standardization effort for Sigma protocols.
- I have supervised a DAAD RISE stipend student. The internship resulted in 🥶 Subzero, a zero-knowledge compiler for Cryptimeleon.
- I am currently doing research with subproject 🪰 C1 in the SFB 901. Research on privacy-preserving crypto, in particular anonymous authentication.
I have been invited to speak at:
- 11th Heinz Nixdorf Symposium - Secure and Privacy-Preserving Services Workshop (2022)
I wrote reviews for:
- Eurocrypt 2022
- Security and Communication Networks (2022)
- CCS 2019
- CT-RSA 2019
- AsiaCCS 2018
