I am currently a researcher at Huawei Singapore Research Center. My research topics include LLM model, image & video super resolution, 3D hand and object object reconstruction. Previously, I was a Ph.D student in the Computer Science Department at National Uinversity of Singapore, supervised by Prof. Angela Yao .  Before that, I did my Master in the College of Intelligence and Computing at Tianjin University, supervised by Prof. Changqing Zhang and Qinghua Hu.

Research Field

My research focuses on 3D Computer Vision and Deep Learning. Specifically, I have been working on 3D hand pose and shape reconstruction and hand-object interaction refinement. I am also interested in multi-label learning, mutli-view understanding, and diffusion model for 3D object pose reconstruction.
