Teacher / Researcher

About Me

I am an Assistant Professor in the Post-Quantum Cryptography Migration Interdisciplinary Lab (PQC-X) at Xi'an Jiaotong-Liverpool University (XJTLU).

I received my Ph.D. from the Institute of Information Engineering, Chinese Academy of Sciences (IIE, CAS) and the School of Cyber Security, University of Chinese Academy of Sciences (UCAS).

Research

My research focuses on cryptography, particularly fully homomorphic encryption (FHE), including its mathematical foundations, practical implementations, and applications.
