I am a senior engineer at Linden Lab, working on improvements to the Second Life viewer. Before that, I worked for six years at Pixar Animation Studios as a lead engineer within the Studio Tools software department, and for five years before that I did 3D computer graphics research at SRI International. I hold a Ph.D. in Computer Science, am the author of over 40 articles, and have written a book on computer graphics. This website describes some of my work and distractions . . .
