Marcus Peacock is a visiting scholar at George Washington University. He is the former minority staff director at the U.S. Senate Committee on the Budget and a former Deputy Administrator of the United States Environmental Protection Agency (EPA). He served at the EPA from August 8, 2005 to January 20, 2009.
Peacock received a Bachelor of Science degree in Industrial and Systems Engineering from the University of Southern California and a Master of Public Policy from Harvard University's John F. Kennedy School of Government. He is a Fellow of the National Academy of Public Administration and a senior member of the Institute of Industrial Engineers.
During his tenure Peacock overhauled EPA’s performance management system. This included publishing a quarterly performance report to the public called the EPAStat Quarterly Report, the first ‘Stat’ program in the federal government. EPAStat copied performance management systems used by local governments, such as "CitiStat" in the City of Baltimore. These improvements led to EPA winning the President’s Quality Award for Overall Management,“the highest award given to federal agencies for management excellence,” in 2007 and 2008. It is the first time a federal agency has won the award back-to-back.Peacock was an early adopter of Web 2.0 technology in government and was the first federal political appointee to maintain a public blog.
