The Santa Fe Institute is an independent, nonprofit research and education center that leads global research in complexity science. SFI scientists seek the shared patterns and regularities across physical, biological, social, and technological systems that give rise to complexity—in any system in which its collective, system-wide behaviors cannot be understood merely by studying its parts or individuals in isolation. Insights from complexity science are increasingly useful in understanding questions far beyond the boundaries of traditional academic disciplines—urban sustainability, disease networks, and financial risk, to name a few.
