Muller said in a release the national security branch will aim to integrate intelligence into operations under Douglas’ leadership.
Douglas most recently served as special agent in charge of the San Francisco division, where she has also served as assistant special agent in charge and oversaw counterintelligence and security programs.
In 2007, she became an inspector at FBI headquarters, handling national security matters and conducting field office and headquarters inspections.
She was promoted to deputy assistant director of the counterintelligence division in 2008 and there she held responsibility for strategy, budget and personnel resources.
Douglas joined the bureau in 1989 in the Washington field office and the bureau credits her with helping carry out espionage investigations and prosecutions of FBI Supervisory Special Agent Earl Pitts and CIA officer Harold James Nicholson.
