Stuart Alan Kauffman (28 September 1939) is an American theoretical biologist and complex systems researcher concerning the origin of life on Earth. He is best known for arguing that the complexity of biological systems and organisms might result as much from self-organization and far-from-equilibrium dynamics as from Darwinian natural selection.

Kauffman presently holds a joint appointment at the University of Calgary in Biological Sciences and in Physics and Astronomy, and is an Adjunct Professor in the Department of Philosophy . He is also an iCORE chair.

He graduated from Dartmouth in 1960, was awarded the BA(Hons) by Oxford University in 1963, and completed a medical degree (M.D.) at the University of California, San Francisco in 1968. After a brief medical career, he moved into developmental genetics, holding appointments first at the University of Chicago, then at the University of Pennsylvania from 1975 to 1995, where he rose to Professor of Biochemistry and Biophysics. Kauffman held a MacArthur Fellowship, 1987-1992.

Kauffman rose to prominence through his association with the Santa Fe Institute (a non-profit research institute dedicated to the study of complex systems), where he was faculty in residence from 1986 to 1997, and through his work on models in various areas of biology. These included autocatalytic sets in origin of life research, gene regulatory networks in developmental biology, and fitness landscapes in evolutionary biology.

In 1996, Kauffman started BiosGroup, a Santa Fe, New Mexico-based for-profit company that employs complex systems methodology to attempt to solve business problems. BiosGroup was acquired by NuTech Solutions^[1] in early 2003. As of 2003, Kauffman was a director of NuTech.

Kauffmann is best known for arguing that the complexity of biological systems and organisms might result as much from self-organization and far-from-equilibrium dynamics as from Darwinian natural selection.

Some fellow biologists working in Kauffman's area reserve judgement on Kauffman's claims about self-organization and evolution. A case in point is the introduction to the 2002 book "Self Organization in Biological Systems".^[2]
