The MIT Laboratory for Financial Engineering is a research center focused on advancing the theory and practice of financial engineering and technology. Drawing on a diverse set of disciplines—finance, computer science, cognitive sciences, biology, medicine, and engineering—LFE researchers are developing new insights into financial market dynamics and how these dynamics can be shaped to improve the efficiency of the financial system and benefit society. LFE projects fall into five broad categories: healthcare finance, foundations of human behavior and financial market dynamics, fintech and AI, asset-market dynamics, and risk management. We also actively engage with industry and public policy.
