Short Bio

I am a Ph.D. student in Computer Science advised by Prof. Yan Yan at University of Illinois Chicago since 2023 Spring. Before that, I received my bachelor’s degree in Mathematics (Information and Computing Science) from Sun Yat-sen University in 2022.

My research interests include 3D Vision, Efficiency, and Explainability.
