My name is Jiahe Chen, and I am currently a first-year Ph.D. student at Zhejiang University.

My research interests include Machine Learning, Computer Vision, and Vision-Language Models. I am especially interested in semi-supervised learning, reinforcement learning, and Agent.

I am fortunate to work closely with Qiyuan Chen, Qian Shao, and many outstanding collaborators from academia and industry.
