Changjing Liu (刘常靖)

Hello, I'm Changjing Liu (刘常靖), a PhD student at The Chinese University of Hong Kong (CUHK), advised by Prof. Hongliang Ren. My research focuses on medical robotics, world model, and perception/simulation. Welcome to my homepage!

Previously, I received my M.Sc. in Instrument Science and Technology from Shanghai Jiao Tong University (SJTU), where I worked on medical robotics and simulation with Prof. Zhiwu Wang and Prof. Guozheng Yan; and my B.Eng. in Mechanical Engineering (Top 5%) from Tongji University in 2021, focusing on drone visual tracking with Prof. Changhong Fu in the Vision4Rbotics Group.

I'm looking for collaboration in robotics, world model, and perception/simulation. Find my CV here, or reach me at changjing.liu@qq.com / changjing.liu@outlook.com.
