The New England Complex Systems Institute is an independent research and educational organisation based in Cambridge, Massachusetts that studies how interconnected systems behave and change. They use advanced mathematics to understand patterns in society, organisations and global challenges, offering insights that traditional science cannot provide. They offer certificate programmes, custom solutions and research in areas including healthcare, education, social policy and international development. They would suit organisations or individuals looking to understand complex problems across social, biological or organisational systems, or those needing to refer clients who need specialist knowledge in complexity science and its real-world applications.
