About Me

Hi! I am currently a second-year Master student at Xiamen University, under the supervision of Prof. Yang Lu.

I am broadly interested in Multi-Modal LLMs, Parameter-Efficient Fine-Tuning, and Long-Tailed Learning. My goal is to develop robust fine-tuning frameworks that enable foundation models to generalize in complex, real-world settings.
