Ruyi Zha (查如一)

I am a 4th year PhD student at the Australian National University (ANU), advised by Prof. Hongdong Li. Previously, I obtained Bachelor of Engineering (First Class Honours) from ANU in 2020.

My primary research interest lies in 3D computer vision, with a focus on 3D reconstruction, neural rendering, and medical imaging.
