I am currently a research assistant professor at the Department of Computing, The Hong Kong Polytechnic University (PolyU). Before joining PolyU, I was a post-doctoral fellow at the Department of Computer Science, the University of Hong Kong. I received my Ph.D. degree from PolyU in 2020 under the supervision of Prof. Man Ho Allen Au.
I am interested in:
Post-Quantum Cryptography
Zero-Knowledge Proofs
Blockchain Technology
