Hi, I'm Joost

As of June of 2015, I'm a PhD student in the Digital Security group of the Radboud University in Nijmegen, The Netherlands. I'm working on post-quantum cryptography (initially as part of the PQCRYPTO project) under the supervision of Peter Schwabe, focusing on software implementations. Before that, I was a Master student at the Radboud University, in the Kerckhoffs programme.
