Jiachen Fu (付嘉晨)

I am a third-year undergraduate student at the VCIP Lab, Nankai University, advised by Prof. Chongyi Li and Prof. Chunle Guo. Since September 2023, I have been enrolled in the Elite Class of Computer Science at Nankai University.

My research interests lie in Large Language Models (LLMs) and Vision-Language Models (VLMs). I have worked on topics in multimodal large models and Trustworthy AI. I also serve as a reviewer for the top journal IEEE TPAMI.
