About

I am a postdoct research fellow in applied cryptography, working in the Surrey Centre for Cyber Security (SCCS) group of University of Surrey, 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.
