Changjing Liu (刘常靖)

Hello, my name is Changjing Liu (刘常靖), currently a PhD student at The Chinese University of Hong Kong (CUHK). Welcome to my homepage!

My current research interests mainly focus on medical robotics and perception/simulation algorithm, supervised by Prof. Hongliang Ren.

Previously, I was a master's student at Shanghai Jiao Tong University (SJTU), Shanghai, China, majoring in Instrument Science and Technology. My master's research focused on medical robotics and medical simulation, supervised by Prof. Zhiwu Wang and Prof. Guozheng Yan.

Prior to this, I graduated from Tongji University in Shanghai, China, in 2021 with a bachelor's degree in mechanical engineering (Mechatronics), and seized the award of the First Prize Scholarship at Tongji University (Top 5%). During my undergraduate studies, I mainly focused on drone visual tracking under the supervision of Prof. Changhong Fu in the Vision4Rbotics Group.

I'm looking for collaboration opportunities in the field of robotics and perception/simulation algorithm, etc. Click here to find my up-to-date CV.

If you have any questions, don't hesitate to contact me via changjing.liu@qq.com or changjing.liu@outlook.com.
