About Me

I am an Associate Professor in the School of Computer Science at University of Birmingham in the UK as of 2024. My research interests focus on Artificial Intelligence for Computer Vision and Graphics, including 3D/4D contents representation/capturing/generation, 3D/4D digital human, image/video generative models, multi-modal foundation models, interpretability and reliability of AI models, etc.

Previously, I served as the Head of AI at Unity China. Before that, I spent over six years at Tencent AI Lab, where I held the position of Principal Research Scientist and Manager. I was an Algorithm Engineer at DJI from 2015 to 2016 and a Research Intern at Adobe from 2013 to 2014. I received my Ph.D. degree in Computer Science from City University of Hong Kong in 2015, and my M.S. degree in Pattern Recognition and Intelligent Systems from Huazhong University of Science and Technology in 2011.
