Biography

I am a PhD student at School of Computing and Data Science, The University of Hong Kong, supervised by Prof. Lequan Yu and Prof. Guodong Li. Before that, I obtained my BSc degree from Faculty of Science, HKU in 2024.

My research aims to understand and automate intelligence for human benefit. Specifically, I focus on: (1) Agentic AI; (2) Trustworthy large multimodal models; (3) Medical AI; (4) Graph representation learning.
