Hi, I'm Jeffrey! I'm a second year PhD student at the University of Cambridge supervised by Professor Ayush Tewari. Previously, I was a research engineer at the GraphDeco group in INRIA with Professor George Drettakis. I was also an active contributor to gsplat.
Before this, I worked on autonomous vehicles and building the perception system for autonomous trains at Parallel Systems in Los Angeles. I received my undergraduate and Master's degrees in Electrical Engineering and Computer Science at MIT with Professor Antonio Torralba.
I am deeply interested in 3D computer vision, computer graphics, and differentiable rendering. I want to capture and build generative models for the real world.

Improved densification strategy for 3DGS.
Use bilateral grids to model changes in camera exposure and other ISP effects for gaussian splats.
Use image compression to compress gaussian splats.
Interpret the z-axis of 3D Gaussians as their normal vector to achieve a similar effect to 2DGS.
