I'm currently pursing my B.A. in Mathematics and CS, through the College Scholars program at Cornell University.

I'm extremely fortunate to work with professor Kevin Ellis. I previously worked with Abe Davis on time-lapse generation and modal analysis for resimulation.

I'm interested in the intersection of physical simulation, machine learning (code generation), and tools for computer graphics. Currently I'm working refactoring and code generation for physical simulation.

I've recenly started writing summaries of my readings on physical simulation.

Projects

Here are some of my research and engineering projects, or at least the ones that are not being prepped for publications...

MLS-MPM and CPIC (2025)

Implemented the Moving Least Squared Material Point Method, CPIC, various materials, as well as mesh extraction, both in 2D and 3D.

GitHub

Image Space Modal Basis in JS and Python (2024)

Implements the 2015 paper "Image-Space Modal Bases for Plausible Manipulation of Objects in Video" by Davis et al., extending the original work with modal warping. Developed modal analysis pipeline in Python and custom JavaScript rasterizer for real-time rendering.

GitHub (Coming Soon)

Obstruction Removal - SliceSplatting (2024)

Modifies Gaussian Splatting to remove obstructions blocking the view of objects of interest in 3D scene reconstruction.

GitHub (Coming Soon)

Pen-2-Graph (2024)

Automates generation of node-edge graph programs from hand-drawn sketches using vision-language models and differential evolution. CS 6172 Final project.

Path Tracing in OCaml (2025)

Implementation of a path tracer in OCaml. Includes distributive ray tracing, reflections, refractions, volumetric elements, emissive objects, BVH, and various object and material primitives.

GitHub

MelodyMesh (2023)

3D music visualizer that deforms meshes based on audio frequencies. CS 6682 Final project.
