Yuanyuan Gao | 高源远

I am a Master's student in the School of Automation at Northwestern Polytechnical University (NWPU), affiliated with BRAIN Lab, advised by Prof. Dingwen Zhang and Prof. Junwei Han. I had the honor of working with Zhihang Zhong and Xiao Sun, who provided invaluable guidance and support. I will join the Department of Computer Science and Engineering at HKUST as a Ph.D. student in Fall 2026, advised by Prof. Dan Xu.

My research interests lie in Vlm, Spatial Intelligence, 3D Gaussian splatting.
