Ruida Zhang (张睿达)

I am a third-year Ph.D. student at Tsinghua University, supervised by Prof. Xiangyang Ji. Previously, I received my B.E. degree in Automation Engineering at Tsinghua University.

My research interest lies in 3D computer vision, including object pose estimation, 3D reconstruction and scene understanding.

I served as a reviewer for CVPR, ICCV, ECCV, RAL, TCSVT, TIM.
