Aaron Brown

Quantitative risk manager at AQR Capital — and author of two books on risk that treat poker, finance, and risk management as aspects of the same underlying discipline.

Risk as unified field: Brown's Red-Blooded Risk and The Poker Face of Wall Street argue that proper risk-taking (at poker, in financial markets, in life) requires the same cognitive architecture — accepting variance, sizing bets correctly, managing emotions about randomness. The 'red-blooded risk' frame opposes both recklessness and risk-aversion: real risk management is not about eliminating variance but about taking calculated variance at the right scale. Popular in quantitative finance and rationalist circles for making risk management philosophically coherent.
