Office of Investigations

Field Offices

The Office of Investigations is responsible for conducting investigations on allegations of crime, cyber-crime, fraud, waste, abuse, and misconduct having impact on NASA programs, projects, operations, and resources. OI refers its findings either to the Department of Justice for prosecution or to NASA management for action. Through its investigations, OI identifies crime indicators and recommends effective measures for NASA management that are designed to reduce NASA's vulnerability to criminal activity. The Office of Investigations is comprised of Headquarters and four geographic Field Offices including a Computer Crimes Division. See link to Field Offices for investigative and geographical areas of responsibility.


The Eastern Field Office is responsible for conducting criminal investigations in which NASA is a victim. The EFO also performs investigations involving waste and mismanagement.
