About Me

Currently, I am a postdoctoral-fellow at NTT Social Informatics Laboratory in Tokyo, Japan. If I ever get a website there, I will link it here too… ;)

In 2025, I completed my Dissertation while being a researcher and teacher at the of the KASTEL Cryptography and Research Group.

My research interest are crypt-analysis, post-quantum cryptography and quantum-annoying PAKEs.

I love to travel and explore new cultures, and I used to have travel blog which I will continue here soon. I also love cooking — but I am a bit lazy when it comes to writing content on this website ;)
