Donald Saari

Donald J. Saari is a Distinguished Professor of Economics and Mathematics at the University of California, Irvine, where he also directs the Institute for Mathematical Behavioral Sciences. His research primarily focuses on mathematical astronomy, particularly chaotic dynamics, which originated in the late 1800s to explain unexpected behaviors in the Newtonian three-body problem. Saari's work encompasses a wide range of topics, including the evolution of the universe, singularities, collisions, and dark matter. After moving from Northwestern University in 2000, he expanded his research interests to include the dynamics of social and behavioral sciences, revealing complexities that can surpass those found in physical sciences.
