Biography

I received my Ph.D. in Computer Science from the University of Sydney (USYD) in 2026, advised by Prof. Tongliang Liu. I received my bachelor's degree in Communication Engineering from Hunan University in 2022. My research interests include trustworthy and causal machine learning, generative models, agentic AI, and machine learning systems, as well as applications of machine learning to scientific and engineering problems.
