Dr. Michael Meyer

I am a postdoc at University of Regensburg, Germany, in the QPC research group of Juliane Kr?mer.

Before that, I was a PhD student at RheinMain University of Applied Sciences and University of Würzburg, Germany, supervised by Steffen Reith and J?rn Steuding, and received my PhD from University of Würzburg. During my PhD, I spent five months in Juliane Kr?mer’s research group at TU Darmstadt.

I received my M.Sc. in Mathematics and B.Sc. in Computational Mathematics at Würzburg University. During my master programme, I spent one semester at Aristotle University Thessaloniki, Greece.


Research interests

My research focus is isogeny-based post-quantum cryptography and elliptic curve cryptography.
