I'm a 3D computer graphics software developer. I started in this industry in 1986 after graduating with a Bacherlor's degree from University of Michigan. I am currently the president of Skew Matrix Software.

My specialty includes OpenGL and scene graph rendering technology. Publications include OpenGL Distilled, OpenSceneGraph Quick Start Guide, and (with Bob Kuehne) OpenSceneGraph Reference Manual. I hold a U.S. software patent in geometric data compression and was the recipient of a 2010 R&D 100 award.
