Kai He (何开)

I am a first-year PhD student at the University of Toronto, supervised by Prof. Igor Gilitschenski. I am current working as a research scientist intern at NVIDIA Toronto AI Lab.

Prior to my Ph.D. studies, I received my bachelor degree at ShanghaiTech University majoring in computer science and technology. I am fortunate to work with Prof. Jingyi Yu and Prof. Lan Xu during my undergraduate studies. I also spent an exciting summer in 2023 at Carnegie Mellon University as a research intern advised by Prof. Sebastian Scherer.

Research

My research interests lie in 3D vision, particularly 3D/4D Generative Models and Neural Rendering. My current research focuses on the controllable generative models for rendering. Additionally, I am exploring to distill pre-trained diffusion models for editing and manipulation.
