ABOUT

I am a Marie Skłodowska Curie Fellow at the Technical University of Munich in the group of Professor Antonia Wachter-Zeh and at Eindhoven University of Technology in the Mathematical Communication Theory group of Professor Alberto Ravagnani. I obtained my Ph.D. in Mathematics at the University of Zurich under the supervision of Professor Joachim Rosenthal. My research interests include cryptography, algebraic coding theory and number theory.

We are happy to announce the second edition of the ACT Summer School

and Coding theory and cryptography- a conference in honor of Joachim Rosenthal's 60th birthday

See me chairing at MWCC

You can find the slides of our sessions at MTNS 2022 here
