Biography
I am a PhD student at Ruhr University Bochum under the supervision of Eike Kiltz and Peter Schwabe. My current research concerns post-quantum public key cryptography with a particular focus on isogeny based cryptosystems. My second research area involves computational models like the Algebraic Group Model.
I served as a reviewer for the following conferences:
- CRYPTO 2023
- TCC 2023
- ESORICS 2023
In my free time I enjoy taking photos, especially of insects.
