Jiale Xu

I am currently a senior researcher at Tencent ARC Lab, working on 3D Generative AI. I obtained my Ph.D degree at ShanghaiTech University in 2024, advised by Prof. Shenghua Gao. Before that, I received my Bachelor’s degree in Computer Science from Harbin Institute of Technology in 2019.

From 2022 to 2024, I was a research intern at Tencent, working closely with Xintao Wang and Yan-Pei Cao.

My research interests are 3D reconstruction and generation, with the goal of providing high-fidelity 3D digitization and ready-to-use 3D contents.

If you are interested in research intern opportunities or collaborations, feel free to drop me an email.
