About

I am a first-year PhD student at the Institute of Computing Technology, Chinese Academy of Sciences. I obtained my bachelor's degree in Artificial Intelligence from Sichuan University in June 2025. In the early stages of my research, I was a research intern at TeleAI, China Telecom, focusing on developing safer and more personalized text-to-image models. During this period, I was fortunately advised by Jinbin Bai and Kaidong Yu, and I received significant support from them.
