Info
I'm a postdoc at the Institute of Information Science of Academia Sinica, Taipei, Taiwan.
Before that, I was at the Max Planck Institute for Security and Privacy, Bochum, Germany.
Before that, I was at the Digital Security group at Radboud University, Nijmegen, The Netherlands.
Before that, I was at the University of Surrey, Guildford, United Kingdom.
In 2022, I obtained my PhD from Radboud University, Nijmegen, The Netherlands under the supervision of Peter Schwabe and Bo-Yin Yang. My dissertation on Polynomial Multiplication for Post-Quantum Cryptography is available here.
In 2017, I obtained my MSc in IT Security from TU Darmstadt under the supervision of Juliane Krämer and Denis Butin.
My master thesis is available here.
I'm part of the UOV and MAYO teams working on submissions to the NIST PQC digital signature on-ramp.
I have also been co-submitter of the Rainbow (RIP) signature scheme which was a finalist in the NIST PQC project.
