I am a third-year PhD student at the School of Computing, National University of Singapore, where I am fortunate to be advised by Professor Angela Yao. Previously, I am graduated in Turing Programme with Highest Distinction in Computer Science from the same faculty. My research is centered on developing efficient and controllable visual-centric generative models. I am particularly interested in understanding and modeling visual signals, as they are easy to obtain and can serve as observations of the real world with minimal inductive bias.

Before beginning my doctoral studies, I co-founded a local company Huijian Cloud in Guangzhou, where we developed AI agent solutions with real-world applicability, including PMS, IMS, and CRM platforms. The company has served clients across Mainland China, Malaysia, Thailand, and Australia. I was also a Fellow of MiraclePlus in 2021.
