I am a research scientist at OpenAI working on multimodal generative models. I recieved my PhD in Computer Science from Brown University, where I was advised by Professor Daniel Ritchie. My work was supported by the NSF Graduate Research Fellowship Program. I received my BS in computer science from The University of Texas at Austin in 2021, where I worked with Professor Chandrajit Bajaj. In my free time I enjoy creating 3D art.

ACM Transactions on Graphics (Proceedings of SIGGRAPH Asia), 2025

A new neural architecture for learning on surfaces that overcomes several key deficiencies in existing methods. We demonstrate its ability to learn deformations of detailed, high-resolution meshes, as well as semantic segmentation.

ACM Transactions on Graphics (Proceedings of SIGGRAPH), 2024

A data augmentation strategy that enables diffusion models to smoothly interpolate between disjoint data modes. We train a diffusion model to blend multiple types of procedural noise patterns, even in the absence of "in-between" training data.

Panopti: Interactive 3D Visualization in Python
[ GitHub / Documentation / PyPI ]

A Python package for interactive 3D visualization that seamlessly supports remote development setups (e.g. through SSH) and headless rendering.


Torch Mesh Ops: PyTorch CUDA extension for discrete differential operators
[ GitHub ]

CUDA kernels that accelerate construction of discrete differential operators on meshes, very useful e.g. when used in a training loop for geometric problems.


torchrbf: Radial Basis Function Interpolation in PyTorch
[ GitHub / PyPI ]

A PyTorch-based RBF Interpolator that supports auto-diff and is much faster than SciPy's CPU implementation.


Renderings

In my free time, I enjoy creating 3D renderings and physical simulations using various software. More can be found here. The programs and tools that I use include: Blender, Cinema 4D, RealFlow, Vray, Octane, Arnold, Krakatoa, and more.
