I'm interested in Computer Graphics and Computational Geometry, and work with Tom Funkhouser and Vladlen Koltun. My research focuses on richer tools for 3D content creation, particularly for novice and casual users. This research is driven by a more abstract interest in shape understanding at both the structural and semantic levels (why is a model of a cow not one of a chicken, what parts of a cow correspond to those of a chicken, how does one morph a cow into a chicken, etc.). I also like rendering scenes with many billions of polygons in real time.

Notes

Survey of some image-based rendering papers (not very polished)

Utilities (public-domain, unrestricted use)

SCGrep: Source-Control Grep: omits results from SVN and CVS subdirectories from (recursive) Grep output. Not quite a drop-in replacement but close.
catalog: Quickly generates a very basic HTML catalog, with track durations, for folks who organize their mp3's as Artist/Album/Track.mp3 (e.g. iTunes). Navigate to root directory of collection and run "catalog > output.html". Uses filename instead of ID3 tag for tracks (I get a lot of unpublished music without ID3s). Requires Perl.
