👋 About me

I am a Ph.D. candidate in Cyberspace Security at Beijing Electronic Science and Technology Institute, supervised by Prof. Yatao Yang. I am currently a CSC-funded visiting Ph.D. student at Nanyang Technological University (NTU), Singapore, advised by Prof. Chip Hong Chang (IEEE Fellow). I am fortunate to be advised by Dr. Shuai Zhao and enjoy collaborating with Dr. Xuan Feng and Dr. Yanhao Jia.

🤔 My research interests include trustworthy AI, model security, backdoor attacks and defenses, and large language models.

🤝 Looking for collaboration. If you are interested in working with me on trustworthy AI or LLM security, please drop me an email.
