I am a Postdoctoral Researcher at The University of Western Australia. I received my Ph.D. in Engineering from Hunan University, supervised by Professor Yaonan Wang and Professor Ajmal Mian. During my Ph.D., I was a joint doctoral researcher at UWA.
My research focuses on 3D/4D generative models, scene understanding, and robotic measurement. I am interested in geometry-aware generation and structured representations that capture the shape, semantics, and dynamics of the 3D world.
