Yujia Zhang （张宇嘉）

Hi, I'm Yujia, a third-year PhD student at The University of Hong Kong, where I work on 3D understanding and representation learning. I am advised by Hengshuang Zhao and Yizhou Yu. I work closely with Naiyan Wang at Xiaomi.

Previously, I received my bachelor's degree (2020-2024) from Zhejiang University in Control Science and ACEE in Chu Kochen Honors College.

Research

I am interested in learning representations of space, motion, and physical rules from video and other observations. I aim to explore how these representations can support active perception and action planning, helping machines recognize changes in their surroundings, decide what to observe next, and choose actions to accomplish real-world tasks.

For a complete list of my publications, please see my Google Scholar profile.
