I work at the intersection of computer graphics, vision, and machine learning, where I build neural surrogate models to simulate the physical world, and I’ve recently become interested in multimodal post-training : )
I’m always happy to chat or explore ideas for collaboration. Feel free to email me anytime!
We adopt Gaussian surfels as the primitives and build an efficient framework for differentiable light transport, inspired by classic radiosity theory, enabling efficient relighting and geometry reconstruction.

SIGGRAPH, 2024
We present a method that uses arbitrary neural network architectures as control variates with automatic differentiation to create unbiased, low-variance, and numerically stable Monte Carlo estimators for various problem setups.
Using neural field caches to reduce variance in Monte Carlo PDE solvers. Our method excels when computing is limited and enables effective bias and variance trade-off.
Introducing a Basis Transformation Method to avoid backfilling in learning new representations for modern retrieval systems.
