Zhenjun Zhao (赵祯俊) I received my PhD from the Chinese University of Hong Kong (CUHK), under the supervision of Ben M. Chen. I am currently working at Unmanned Systems Research Group lead by Ben M. Chen at CUHK. I have been fortunate to collaborate with others, including Haoang Li from HKUST (Guangzhou) , Chen Wang from University at Buffalo (UB), and Peidong Liu from Westlake University.

My research work mainly lies at the intersection of robotics and 3D computer vision, with the applications to robotics, autonomous driving, virtual reality and augmented reality etc. Currently I am exploring how to best integrate machine learning techniques (i.e. mainly deep learning) with classical geometry-based 3D visual perception pipelines to improve their performance, especially under extremely challenging conditions. In particular, design algorithms that better blend geometric inductive bias and powerful data-driven approaches.
