Chengkun LI

Macao Polytechnic University Ph.D. student, the Chinese University of Hong Kong

I am Chengkun L, I am the final-year Ph.D. candidate at the Chinese University of Hong Kong (CUHK) and work under the supervision of Prof. Qi Dou and Prof. Jason Ying-Kuen Chan. My research bridges 3D Computer Vision and Surgical Robotics, focusing on reconstruction, neural rendering, and generative AI for surgical area.

Prior to my Ph.D., I obtained my M.Sc. in Computer Graphics, Vision and Imaging with Distinction from University College London (UCL) and my B.Eng. from Beihang University (BUAA).
