My interests center around using procedural models (computer programs) to simulate complex natural phenomenon. Such models can aid scientific understanding of the phenomenon. They also allow us to recreate and control the phenomenon for use in animation, games and the arts.

A main theme of my work as been to write software that simulates various types of human and animal behavior. These programs control the actions of autonomous characters in virtual worlds. I started by simulating bird flocks and related group behaviors. That approach was generalized to other kinds of goal directed steering behaviors. Most recently I have applied these ideas to models of emergent teamwork in crowds, such as collective construction based on stigmergy, as seen in social insects.

I am also interested in using evolutionary computation to design procedural models, such as for behavioral control and texture synthesis. A key aspect of this is the design of the criteria for evolution of subtle properties that are hard to define. My recent work in this area involves modeling the evolution of camouflage in nature.

Since 1998 I have worked at the US R&D group of Sony Computer Entertainment near San Francisco, California.
