Searching for Order in the Complexity of Evolving Worlds
Our researchers endeavor to understand and unify the underlying, shared patterns in complex physical, biological, social, cultural, technological, and even possible astrobiological worlds. Our global research network of scholars spans borders, departments, and disciplines, unifying curious minds steeped in rigorous logical, mathematical, and computational reasoning. As we reveal the unseen mechanisms and processes that shape these evolving worlds, we seek to use this understanding to promote the well-being of humankind and of life on earth.
What is Complex Systems Science?
Complexity arises in any system in which many agents interact and adapt to one another and their environments. Examples of these complex systems include the nervous system, the Internet, ecosystems, economies, cities, and civilizations. As individual agents interact and adapt within these systems, evolutionary processes and often surprising "emergent" behaviors arise at the macro level. Complexity science attempts to find common mechanisms that lead to complexity in nominally distinct physical, biological, social, and technological systems.Learn More

Founded in 1984, the Santa Fe Institute was the first research institute dedicated to the study of complex adaptive systems. We are operated as an independent, nonprofit 501(c)(3) research and education center.Learn More
The Santa Fe Institute’s Cowan Campus is located in Santa Fe, New Mexico in the foothills of the Sangre de Cristo mountains.
SFI’s Miller Campus in Tesuque, NM was inaugurated in November 2019 by Bill Miller, SFI Life Trustee and Chairman Emeritus.
SFI in Winter
SFI's campuses are home to about 50 researchers and staff and host over 1,000 visitors annually.
An abundance of glass walls offer impromptu writing space.
Caves and Commons
Both campuses combine traditional office spaces with with open areas for collaboration.
Rain over Tesuque
Surrounded by hiking trails, both SFI campuses enjoy breathtaking views of the New Mexico landscape.
