John Coates is a neuroscientist at the University of Cambridge and former Wall Street trader for Goldman Sachs, Merrill Lynchand Deutsche Bank.
Coates' research focuses on the hormonal basis of financial decision making, inspired by his own experiences trading. He describes how men trading "display what may be called [the] classical clinical symptoms of mania. They were delusional, they were euphoric, they were over confident, they had racing thoughts [and a] diminished need for sleep."
In 2012, Coates published The Hour Between Dog and Wolf: how risk-taking transforms us, body and mind.
