Alan Liang

I am a 4th-year PhD student in Shenyang Institute of Automation , Chinese Academy of Sciences advised by Prof. Huaici Zhao. Now, I am a visiting student at NUS advised by Prof. Wei Tsang Ooi.

Research Interest: I focus on 3D/4D perception for autonomous driving and robotics. I develop robust yet lightweight models to meet unmanned systems’ strict safety and real-time requirements. Lately, I’m hooked on 3D/4D generation—using synthetic data to replace tedious collection and annotation. My goal: Generate data more realistic than reality itself and free researchers from grunt work.

Since October 2024, I have been funded by the China Scholarship Council (CSC) to join the Department of Computer Science at the National University of Singapore. I am honored to be advised by Prof. Wei Tsang Ooi. I am also fortunate to collaborate closely with Lingdong Kong (Apple ScholarApple Scholar), Dongyue Lu ("Pineapple Scholar"Pineapple Scholar), and Yu Yang ("Potato Scholar"Potato Scholar).
