Curriculum vitae

🏫 Academic life

2015-2022: PhD student at Paderborn University with Johannes Blömer.
2010-2015: Computer science Bachelor’s and Master’s at Paderborn University (with distinction).

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 (loosely) involved with 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.

For more information, see the research page or take a look at my publications.

I wrote reviews for:
