An end-to-end technical study of opal as a natural photonic crystal, pairing a long-form visual explanation with a purpose-built spectral path tracer. The work spans physical modeling, scientific communication, and interactive rendering.

I design and build spatial computing systems where simulation, physical intuition, and real-time software meet.
Selected work
Systems built from first principles.
Applied research and production engineering across spatial computing, simulation, robotics, and technical visualization.
A real-time spatial visualization system for vector fields, built with procedural tube meshes and numerical field integration. Users place sources in the room and inspect the resulting field through arrows, particles, and persistent trails.
A spatial teleoperation prototype connecting Spectacles hand input to a LeRobot arm. The system explores direct, embodied robot control and the interaction constraints of low-latency hardware interfaces.
An open-source electronics toolchain for spatial computing: KiCad PCB, schematic, and symbol-library parsers; an autorouter; and a fully procedural board renderer. The result turns engineering source files into inspectable spatial models.
An interactive spatial teaching system that makes matrix operations, elimination, rotations, and eigenvalues tangible. The work translates abstract mathematical structure into manipulable, real-time explanations.
