Hi! I am Kejia Zhang, a first-year Ph.D. student at The Hong Kong Polytechnic University, advised by Prof. Yang Liu, Prof. Jiannong Cao, and Prof. Qiang Yang.

Before joining PolyU, I earned my M.S. from Xiamen University, advised by Prof. Zhiming Luo. Earlier, Prof. Haifeng Zhang guided me into research and supported my academic growth. I also collaborated with Jiasheng Tang at Alibaba DAMO Academy and Prof. Huan Wang at Westlake University on hallucination in MLLMs.

My current research focuses on large-small model collaboration and healthcare AI.
