Felix Rohrbach

Welcome

I am a post-doctoral researcher at CISPA Helmholtz Center for Information Security, in the group of Willy Quach. Previously, I obtained my PhD in the Cryptoplexity group at TU Darmstadt, with Marc Fischlin as my advisor.

My research interests include lower bounds of cryptographic primitives and the foundations of cryptography in general.
