Dual Photography (October ’04 – present)
Led a team that developed a novel photographic technique which exploits Helmholtz reciprocity to interchange cameras and projectors in a scene, effectively capturing a photograph from the point of view of the projector. Demonstrated how this technique can capture a 6D slice of the full 8D reflectance field more efficiently than conventional techniques.

Silhouette Maps (Dissertation work) (September ’02 – present)
Developed the silhouette map data structure that embeds boundary information into a texture and can be accessed in real-time. Silhouette maps can be used for conventional texture mapping to reduce the blurring as well as for various other texturing applications, e.g. shadow mapping.
Real-time Shading Languages (September ’00 – September ’02)
Developed back-ends for the Real-time Shading Language (RTSL) for the NV20 and the R300. Created demos that were featured in the cover of the Graphics Hardware 2001 proceedings. Worked on an algorithm to recursively split large shaders into multiple passes to fit them onto the hardware (RDS).
Negative Electron Affinity Photocathodes for E-beam Lithography (June ’97 – June ’99)
During my M.S. degree I worked in the area of semiconductors, experimenting with novel electron sources for high-throughput electron beam lithography. In particular, I studied the effects of contamination on the performance of Negative Electron Affinity (NEA) photocathodes.
Co-founder of a profitable startup company that provided a suite of online tools to efficiently manage promotions online.
Residential Computer Consultant. Configured and maintained the network connection to students’ homes.
Commissariat d’Energie Atomique (CEA), Grenoble, France (Summer ’96)
Developed software to implicit the void function in the latest version of the CATHARE code, a program that simulates a nuclear reactor during accidental conditions.
Space Telescope Science Institute
Wrote software that analyzed spectral data from high-redshift active galactic nuclei (AGN) imaged by the Hubble telescope.
Eastman Kodak, Office Imaging
Designed test fixture to improve the quality of printed circuit boards in the microfilm machines.
Motorola, Land Mobile
Wrote software to manage modules in the memory of a digital two-way radio, a program still used at the company today.
Teaching Assistant, CS448A Advanced Rendering with Professor Pat Hanrahan
Prepared course materials, helped with teaching duties, aided students with final projects.
Teaching Assistant, AA236A Spacecraft Design with Professor Bob Twiggs
Course involved the construction of a small “satellite” by each group of students. I ran the laboratory and helped the students with their projects.
Volunteer teacher one day a week to teach a 5th grade class Math and Science in Spanish. Designed curriculum to cover topics in Science, Engineering, and Mathematics.
Teaching Assistant, EE208 Electronics Laboratory
Designed labs and quizzes, helped students with their assignments.
