Zeyu Cai (蔡泽宇)

I am a PhD student at Nanjing University, in the PCA Lab, supervised by Zhenyu Zhang.

I am fortunate to work with Yuliang Xiu at Endless AI Lab. I got my M.Phil degree from HKUST(GZ) supervised by Zeyu Wang and Ailing Zeng, and got my B.S. from Nanjing University of Aeronautics and Astronautics.

My research topics include computer vision, machine learning, and computer graphics, specifically in Human-Centric AI.

Research

How can AI systems understand and interact with humans in a natural and intuitive way? This fundamental question drives my research in Human-Centric AI, where I focus on developing intelligent systems that can perceive, understand, and generate human-centered content across multiple modalities.

Specifically, I am investigating Human-Centric generation methods that can create realistic human avatars, videos, motions, and behaviors, as well as multimodal perception tasks that enable AI systems to understand human activities, emotions, and intentions from diverse sensory inputs including vision, audio, and text.
