👋 About Me

I am Zexin Feng, a Ph.D. student at the Mobility Transformation Lab, The University of Hong Kong (HKU), Hong Kong SAR, China, supervised by Prof. Xintao Yan. My research focuses on city-scale traffic simulation, autonomous driving, computer vision, and machine learning.

Previously, I earned my B.Eng. in Computer Science from the Southern University of Science and Technology (SUSTech), Shenzhen, China (expected June 2025). During my undergraduate studies, I was a long-term member of the iMED Intelligent Medical Imaging Lab led by Prof. Jiang Liu, and I also worked with Prof. Xiaohui Xie at the University of California, Irvine on AI for healthcare.
