Biography

I am currently a research assistant professor at The Hong Kong Polytechnic University (PolyU) . Prior to this, I obtained my doctoral degree from University of Science and Technology of China (USTC) .
My research interests focus on computer vision and embodied AI, especially Vision-tactile Perception and Manipulation. I actively collaborate with leading industry partners such as Tencent AI Lab, IFLYTEK, Astribot, focusing on cutting-edge research in pose perception. I am a strong advocate of sharing🌱, collaborating🤝, advancing🚀, and innovating💡. Passionate about bridging fundamental research with real-world impact, I strive to ensure my work contributes to both academic progress and practical value.

Researches

My current research focuses on the visual perception of articulated and flexible objects, aiming to develop advanced 3D pose estimation methods to empower robots with fine manipulation and dexterous grasping capabilities. While significant progress has been made in enabling robotic operation in idealized settings, challenges related to robustness and adaptability persist in complex and unstructured environments such as underwater exploration, medical intervention, and industrial inspection. In response to the unique perception demands posed by these scenarios, I am actively expanding my research into new directions, with an emphasis on critical visual perception problems and corresponding solutions for underwater and medical robotics.
