Info

I am the research director at the Taiwanese PQC start-up Chelpis Quantum Tech based in Taipei, Taiwan.
Before that, I was 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 a co-editor of the IACR Cryptology ePrint Archive.
I'm a co-submitter of the UOV and MAYO signature schemes which have been submitted NIST PQC digital-signature competition.
I have also been co-submitter of the Rainbow (RIP) signature scheme which was a finalist in the NIST PQC project.
