Join our scientific revolution!

For more than 35 years, a small team of renowned scientists has been forging a science for the interconnected world. SFI's founders dreamt of an "institute without walls," where scientists could pursue pressing problems without regard to traditional disciplines or funding streams. Today, the Santa Fe Institute, a 501(c)3 nonprofit organization, attracts top researchers from around the globe by creating a culture of unification and connectivity. Our fundamental research has found breakthrough applications to some of society's most pressing problems such as technological development, urban sustainability, and epidemic tracking.

Whether you are a new or seasoned traveler in the complex systems universe, we invite you to connect with us.

Ways to Engage


Our schools and online courses bring complexity science to curiousity-driven individuals, from undergraduates to professionals.

Science Club

Supporters at the Emergence Circle level can engage with our scientists in small-group discussions about timely research.

InterPlanetary Project

Our annual ideas festival celebrates the power of science and human ingenuity to "change the world, one planet at a time."

Complexity Podcast

Far-reaching conversations with a worldwide network of scientists, scholars, and artists to explain our universe's deepest mysteries.

Community Lectures

This free lecture series brings the best minds to Santa Fe to discuss the most profound questions in 21st century science and society.

SFI Press

Our accessible, affordable books tour scientific frontiers, revitalize classic complex-systems texts, and bring SFI's research to the curious public.

ACtioN Network

Firms, governments, and nonprofits can join our membership network, where they learn complex-systems insights to better achieve their goals.


If you are a postdoctoral researcher, one of the best ways to engage with SFI is by applying for a fellowship.


Andromeda Strain

A new video series, “Andromeda Strain and the Meaning of Life,” will explore major questions around astrobiology and life’s origins through imaginative conversations between six leading researchers in the field.

The Puzzles of Politics and Voting

In this talk, Complexity Fellow Vicky Chuqiao Yang gives an overview of her research projects that use mathematical modeling to address some of the most complex issues in American politics.

Why Babies Sleep Longer

Using data from humans and other mammals, a team of scientists, including SFI researchers, has developed one of the first quantitative models that explains why sleep times across species and during development decrease as brains get bigger.

Time Scales and Tradeoffs

In this flash talk, researchers discuss two prominent features of the COVID-19 pandemic—the need to balance very difficult tradeoffs and weight the short-term costs of isolation against the long-term benefits of reducing the burden on essential infrastructure.
