The New England Complex Systems Institute (NECSI) is an independent research and educational institution. We study how interactions within a system lead to its behavioral patterns, and how the system interacts with its environment. Our mathematical tools transcend the boundaries of physical, biological and social sciences, as well as engineering, management, and medicine.
