Emanuel Derman is a professor of finance at Columbia University and also a physicist. But what' he's probably best known for is his years at Goldman Sachs in the lead-up to the financial crisis and his role as one of the pre-eminent Wall Street "quants" — investment professionals who attempted to use complex quantitative models to drive risk out of making money. These days, some critics blame the quants for nearly destroying the global financial system.
Derman chronicled his Wall Street days in a 2004 book, "My Life as A Quant: Reflections on Physics and Finance" — a full four years before the financial crisis truly took hold in late-2008. He's now followed that title up with "Models. Behaving. Badly," in which he looks back on both his life and his life's work and...finds fault with the world that he in part helped to engineer.
