About

I am a postdoct research fellow in applied cryptography, working in the ¿Û¿Û´«Ã½ Centre for Cyber Security (SCCS) group of ¿Û¿Û´«Ã½, collaborating with Professor Liqun Chen. My research topics spans blockchain security, functional encryption, and zero-knowledge proofs (zk-SNARK/STARK), with growing expertise in post-quantum cryptography. I have strong publication record in top-tier venues (USENIX Security, ACM CCS, ESORICS, ACNS) and I am a contributor to international standards (ISO/IEC). Experienced in both theoretical design and practical implementation, with programming skills in Python, Rust, and C/C++. Motivated to bridge cutting-edge cryptographic research with real-world applications.
