He is known for his work on nonlinear systems, including contributions to the study of synchronization in dynamical systems, for his research in a variety of areas of applied mathematics, including mathematical biology and complex network theory, and for his outreach work in the public communication of mathematics. He has an Erdős–Bacon number of 4.
Strogatz attended high school at Loomis Chaffee from 1972–1976. After graduating from Princeton University, summa cum laude, with a Bachelor of Arts degree in mathematics in 1980, he was a Marshall Scholar at Trinity College, Cambridge from 1980–1982, and then received a PhD in applied mathematics from Harvard University in 1986 for his research on the dynamics of the human sleep-wake cycle.
