Stuart Kauffman is an emeritus professor of biochemistry at the University of Pennsylvania and a theoretical biologist who studies the origin of life and the origins of molecular organization. He is a MacArthur Fellow and an external professor at the Santa Fe Institute. Twenty-five years ago, he developed the Kauffman models, which are random networks exhibiting a kind of self-organization that he terms "order for free." Dr. Kauffman is the founding general partner and chief scientific officer of The Bios Group, a company that applies the science of complexity to business management problems. He is the author of The Origins of Order and Investigations and the coauthor (with George Johnson) of At Home in the Universe: The Search for the Laws of Self-Organization
