Kang Liao 廖康

I am currently a Research Fellow at the MMLab@NTU, S-Lab, and working with Prof. Chen Change Loy, Nanyang Technological University (NTU), Singapore. Before joining NTU, I obtained my Ph.D. degree in 2023 at Beijing Jiaotong University (BJTU) in MePro, advised by Prof. Chunyu Lin and Prof. Yao Zhao. I was a visiting scholar at Max Planck Institute for Informatics (MPII) in Computer Graphics Department advised by Vahid Babaei and Prof. Hans-Peter Seidel.

Research Interests

My research interest lies at the intersection of Computer Vision and Deep Learning. In particular, my work focuses on computational imaging and photography, generative models, 3D vision, 360° panoramic scene understanding, etc.
