I am currently a PhD Candidate in the Department of Information Engineering at The Chinese University of Hong Kong, where I am fortunate to be advised by Prof. Raymond Yeung. I received my Bachelor’s degree in Electrical Engineering with First Class Honors from The University of Sydney in 2020. During my undergraduate studies, I was fortunate to work with Prof. Philip Leong on perturbation-based neural network on-chip training.

I have been a reviewer for NeurIPS, CVPR, ECCV, ACM MM, and AAAI. My research focuses on learning and modeling complex systems with AI. I am particularly interested in finding the underlying representation of data and solving real-world problems with interdisciplinary knowledge.
