Ray Lei Yao

I am a PhD student in the Department of Electrical and Eletronic Engineering at Hong Kong Polytechnic University, supervised by Prof. Lap-Pui Chau (IEEE Fellow) and Dr. Yi Wang.

I recieved my BSc and MRes in School of Mechanical Science and Engineering, Huazhong University of Science and Technology advised by Prof. Youping Chen in 2020 and 2023, respectively. I served as a research intern in the Robotics X Lab at Tencent from May. to Oct. 2022.

  • Research

    My current research interests lie in the intersection of 3D Vision and Visual Representation for Embodied AI, with particular interests in 3D scene understanding, sample-efficient and generalizable manipulation policy learning. My research objective is to bulid an embodied agent which has the ability to efficiently perceive and interact with complex real-world environment. Previously, I have worked on robot Compliance control and Nonprehensile manipulation.
