New England Complex Systems Institute (NECSI) is an independent academic research and educational institution at the forefront of advancing analytics and its application to societal challenges. With a focus on complex systems science, NECSI studies how interactions within a system give rise to behavioral patterns and how the system interacts with its environment. NECSI's research extends beyond traditional boundaries, spanning physical, biological, and social sciences, as well as engineering, management, and medicine.

Their interdisciplinary approach utilizes unified mathematically-based tools to overcome the limitations of classical approximations. Through their innovative research, NECSI addresses real-world problems, including social policy matters. Their areas of expertise encompass networks, agent-based modeling, multiscale analysis, complexity, chaos, predictability, evolution, ecology, altruism, systems biology, health care, negotiation, military conflict, ethnic violence, and international development.

In addition to conducting classes, seminars, and conferences, NECSI offers postdoctoral fellowships, online research resources, and hosts the prestigious International Conference on Complex Systems. Through their education initiatives, NECSI aims to contribute to the advancement of science and the betterment of society
