Biography

I am currently a first-year Master's student in Infocomm Security at the National University of Singapore (NUS). I am fortunate to be advised by Prof. Jiaheng Zhang and work closely with Dr. Jipeng Zhang.

Prior to this, I received my B.Sc. degree from Xi'an University of Posts and Telecommunications (XUPT), under the supervision of Prof. Yanqi Zhao.

My research interests include Applied Cryptography, Anonymous Authentication, Zero-Knowledge Proofs and Blockchain Security.

Misc

Beyond research, I am a history enthusiast and deeply fascinated by museums. I served as a volunteer docent at the Shaanxi History Museum, where I enjoyed sharing stories of the past. I also love hiking and photography, capturing moments in nature. I am an easy-going person and always happy to connect and collaborate with others!
