About me
I’m a Ph.D. student advised by Prof. Mingrui Liu at Department of Computer Science, George Mason University since Spring 2023. Before that, I received my master’s degree in compuer science from University of Electronic Science and Technology of China, advised by William Zhu, and bachelor’s degree in EE from Sichuan University. I focus on designing efficient machine learning algorithms for practical problmes, including continual learning, meta-learning and large language model, and provide theoretical guatantees.
Research Interest
Bilevel Optimization, Continual Learning, Federated Learning, Parameter-Efficient Fine-Tuning for LLM.
