I am a Ph.D. candidate at Robotics, Embodied AI, and Navigation In-vivo Lab, Department of Electronic Engineering, The Chinese University of Hong Kong, supervised by Prof. Hongliang Ren. Prior to my doctoral studies, I worked as an Embedded Software Engineer working in the automotive industry at Continental Automotive in Singapore. Before that, I conducted research in Prof. Chengkuo Lee’s lab at the Department of Electrical and Computer Engineering, National University of Singapore and received my M.Sc. degree in 2019. I completed my undergraduate studies in Information Engineering at Soochow University from 2014 to 2018.
My research focuses on efficient & robust medical image analysis and intelligent robotic surgery. I am recently working on Visual Foundation Models, Multi-modal LLM, and Embodied AI.
