Yichong SUN (孙艺崇)

Hi~ Welcome to my personal website! I am a Postdoctoral Fellow at The Chinese University of Hong Kong (CUHK), with the Multi-Scale Medical Robotics Center and the Chow Yuk Ho Technology Center for Innovative Medicine. My research interests lie in medical robotics, with a focus on system design, perception, and control for robotic-assisted surgery.

CUHK MSc students interested in medical robotics and AI are welcome to email me, and so is anyone else. The work is intelligent magnetic medical robotics: learning-based magnetic localization and actuation, magnetic sensing fused with endoscopic vision, medical simulation, and AI-assisted state understanding and task decision-making. We can talk online.
