Congyi Zhang

Postdoctoral Research and Teaching Fellow · The University of British Columbia

prof_pic.jpg

I am a postdoctoral research and teaching fellow in the Department of Computer Science at UBC with Prof. Alla Sheffer. Prior to this position, I served as a research associate at HKU CS working with Prof. Wenping Wang. I also spent a year as a visiting researcher at the Max Planck Institute for Informatics with Prof. Christian Theobalt. I earned my Ph.D. in computer science from Peking University and my B.Sc. in mathematics from Fudan University. My recent research topics are focused on neural shape representation, AI for 3D content generation, human–computer interaction, and 3D reconstruction.

I am an incoming Assistant Professor in the Computer Science Department at UT Dallas and am currently looking for self-motivated Ph.D. students starting in Spring/Fall 2026. If you’re interested in working with me, please feel free to send me your CV.
