Moyun Liu
Postdoctoral Researcher at Huazhong University of Science and Technology working on embodied intelligence, robot perception, and multimodal 3D understanding.
I am currently a Postdoctoral Researcher in the School of Mechanical Science and Engineering at Huazhong University of Science and Technology (HUST), working with Prof. Han Ding (Academician of the Chinese Academy of Sciences), Prof. Bo Tao (Changjiang Distinguished Professor), and Prof. Xingwei Zhao (Recipient of the National Science Fund for Excellent Young Scholars).
I received both my M.S. and Ph.D. degrees in Mechanical Science and Engineering from HUST in 2021 and 2025, advised by Prof. Youping Chen and Prof. Jingming Xie. From 2023 to 2025, I was a visiting student at the A*STAR Centre for Frontier AI Research (CFAR), Singapore, where I worked with Prof. Joey Tianyi Zhou and Dr. Jiawei Du.
My current research interests include embodied AI, humanoid robotics, multimodal fusion, and 3D scene understanding.
Research Focus
Embodied AI
I study how vision-language models and multimodal reasoning can support grounded interaction, affordance understanding, and task-oriented behavior.
Humanoid Robotics
I am interested in perception modules and decision pipelines that improve scene understanding and action planning for humanoid systems.
Multimodal 3D Perception
My previous and ongoing work covers depth completion, 3D detection, segmentation, and cross-modal representation learning across images, point clouds, and language.
