Hongjia Zhai

I am a Ph.D. student (Aug. 2020 - Present) in Computer Science at State Key Lab of CAD & CG of Zhejiang University, advised by Guofeng Zhang and Hujun Bao. Before that, I got my bachelor degree in Automation Engineering from Xi'an Jiaotong University, advised by Xueming Qian.

My research interests lie in 3D computer vision, particularly on Visual Localization, Reconstruction, Scene Understanding, and Embodied AI.

I am looking for postdoc in 3D vision and embodied intelligence. If there are suitable opportunities available, please feel free to contact me.
