Brian Chao
I'm a 3rd year PhD student at Stanford University working in the Stanford Computational Imaging Lab , advised by Prof. Gordon Wetzstein .
I'm grateful to be supported by the NSF GRFP and the Stanford Graduate Fellowship .
My research focuses on computational imaging, displays, and physical optics, and how they
can be combined with modern graphics and 3D-ML techniques (such as NeRF, 3DGS, etc) to create novel AR/VR experiences.
I've interned at Meta Reality Labs, where I worked on 3D reconstruction with Changil Kim .
I've also served as a reviewer for SIGGRAPH, ISMAR, TIP, ICIP, and ICASSP.
