I am currently a first-year Ph.D. student of School of Artificial Intelligence in Nanjing University advised by Professor Yu-Feng Li, and a member of LAMDA Group, which is led by Professor Zhi-Hua Zhou. I received my B.Sc. degree from School of Big Data and Software Engineering in Chongqing University. In September 2025, I was admitted to pursue for a Ph.D. degree in Nanjing University without entrance examination.
My long-term goal is to build practical and robust AI systems in the real world.
My current research interests mainly include Machine Learning, Learnware and Efficient Fine-Tuning for LLMs.
