Hurst, who first joined JPMorgan in 2008 from Morgan Stanley, has joined CEM's physical gas trading team.

Natural gas investments played a big part in generating big profits for Citadel last year with the fund's team of meteorologists helping predict demand for heating fuels.

Prior to Morgan Stanley, Hurst's early career featured quant roles at Bankers Trust Australia and Macquarie, having obtained a PhD in financial mathematics from the Australian National University in 1997.
