About Me

I am a first-year Master student in the School of Informatics at Xiamen University, supervised by Prof. Yang Lu.

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