I am currently a Ph.D. student at the Department of Computer Engineering at the University of Virginia starting from 2023 Fall, advised by Professor Jundong Li. I received my B.E. in Computer Science from University of Science and Technology of China.

My research interests lie in the multi-modal application of Large Language Models.
