In a statement, Joe Mansueto, chairman and chief executive officer of Morningstar, said Cooley is “ready for a new challenge” and is “considering several options, including going back to school to pursue a doctorate or staying with Morningstar in a research capacity.”
“He's going to take some time to think about the next chapter in his life, which I hope will include a role at Morningstar," said Mansueto.
In addition, James Tanner, has joined Morningstar as global head of business development and sales. Tanner most recently served as Markit's vice chairman of business development and before that its head of global distribution.
“We've long admired Jim's customer-centric approach to business. His appointment adds even more firepower to the strong sales management team we have in place," said Mansueto.
