👋 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 Physical AI and Machine Learning, with interests in robot manipulation, generative simulation, autonomous driving, and medical imaging.

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.

If you are interested in my work, please contact me at zexinfeng@connect.hku.hk or mark4551124015@outlook.com.
