About the Office of the Chief Scientist

The Office of the Chief Scientist (OCS) provides leadership and coordination to ensure that research supported by, and scientific advice provided to the Department and external stakeholders is held to the highest standards of intellectual rigor and scientific integrity.

The OCS strives to inform policy and programmatic decisions within the Department by providing the best available scientific advice and input; establishing appropriate linkages between the USDA and other science-performing organizations in government (U.S. and abroad), academia, and industry; and ensuring the dissemination of science performed by the Department to policy makers and decision leaders across the spectrum of policy making nationally and internationally.
