A graduate of Spelman College, Cook has been described by American economist Barry Eichengreen as "part economist and historian," with command of several languages, including French, Russian, Spanish and Wolof - a widely spoken language in Senegal.

Before that, she served as a senior adviser on finance and development in the Treasury Department's Office of International Affairs. 

She joined the Fed board in May 2022 and was reappointed in September 2023 for a term that runs through January 2038.
