Jinkun Cao

I am a Robotics PhD student at CMU with Kris Kitani since 2020.

I received bachelor degree from Shanghai Jiao Tong University advised by Cewu Lu. I visited UC Berkeley in 2019, advised by Trevor Darrell. I also visited Yang Gao's group at Tsinghua University in 2020. I have interned in Nvidia Research, Adobe Research, Meta Reality Labs, Tencent and Bytedance AI Lab etc. My research is supported by Meta PhD Fellowship since 2023.

Research Interest

I am interested in modeling the human motion from interacting with humans, objects and scenes.

Motion and interaction cause visual occlusion and body deformation/articulation. I study how to estimate human motion and the body pose and shape from visual input with noise and ambiguity. I am also interested in building inclusive temporal prior for human motion.
Visual observations are projected from our physical world. I study combining physics-based tools and visual models to enhance the plausibility and fidelity of human motion modeling. I am also interested in the resulting animation and robotics tasks.
