Ken is senior developer at Valve and has contributed to a wide range of projects in the last 15 years, most recently on animation and AI for Half-Life. Previous projects include satellite networking, cryptography, 3D prosthetic design tools, 3D surface reconstruction, and in-circuit emulators. Oddly enough, Ken dropped out of studying EE to pursue a fine arts degree at The Evergreen State College, which he considers far more relevant to creative thinking than any silly differential equations class.
