President-elect Joe Biden has nominated Janet Yellen to be treasury secretary. If confirmed by the Senate, Yellen would be the first woman to hold that post. She would also be the first person to have been both Federal Reserve Chair and treasury secretary. Yellen also served as President of the Federal Reserve Bank of San Francisco and as Chair of the Council of Economic Advisers during the Clinton administration. Prior to entering government service, Yellen was on the economics faculties of Harvard University and the University of California, Berkeley. At the time of her nomination she was a Distinguished Fellow in Residence at the Brookings Institution.
