Po Ryan I am a fourth year PhD student at Stanford University working with Prof. Gordon Wetzstein at the Stanford Computational Imaging Lab. My research lies in autoregressive video generation and video world models. My work is supported by the Stanford Graduate Fellowship. Prior to Stanford, I spent my undergrad in Carnegie Mellon University working with Prof. Ioannis Gkioulekas.
