Research Themes

Monte Carlo, Density Estimation, & MCMC

How do we numerically solve multi-dimensional path-space integrals for realistic image synthesis?

Editing Physically-based Light Transport

Can we devise intuitive controls to edit physically-based lighting in synthetic images?

Basis-space Methods of Dynamics & Lighting

Can we use analytic bases to simulate physical dynamics in reduced-dimensional spaces?

Editing Complex Fluid Simulations

How do digital artists author turbulent fluid simulations? Can we design tools to help them?

Manufacturing Passive Optics & Probes

Can combining computation with 3D fabrication allow us to warp & capture light in the real world?
Visually browse my research highlights, by theme, below.
  • Beam density estimation and many-light methods.
  • Path connection strategies in light transport.
  • Artist tools for digital content creation.
  • Using fabrication to warp light in the real world.
  • Interactive shadows and global illumination.
  • Capturing geometry and reflectance in the wild.
  • Geometry analysis for artistic line drawings.
