On Oct. 1, 2024, the FDA began implementing a reorganization impacting many parts of the agency. We are in the process of updating FDA.gov content to reflect these changes.
The Office of the Chief Scientist (OCS) provides strategic leadership, coordination, and research expertise to support scientific excellence, innovation, and capacity to achieve the FDA public health mission.
Cross-Cutting Functions: OCS leads FDA-wide scientific initiatives and programs to advance FDA science across all FDA-regulated product areas.
Research and Testing: OCS advances public health protection through state-of-the-art science and analysis in its network of laboratories across the country.
Regulation and Coordination: OCS oversees the regulation of cosmetic products and certification of color additives for cosmetics, food, drugs, and devices.

FDA is advancing alternative methods for regulatory use. Alternative Methods have the potential to provide more timely and more predictive information to assess certain aspects of FDA-regulated products while also replacing, reducing and/or refining animal testing (the 3Rs).
Since 2012, FDA has been soliciting proposals through a specialized contract mechanism known as FDA's BAA, which makes it possible for us to solicit innovative ideas and approaches to developing and evaluating FDA-regulated products by tapping into external knowledge and infrastructure in areas where FDA has limited expertise or capacities.
The FDA Grand Rounds is an educational presentation that is webcast monthly to highlight cutting-edge research underway across the Agency and its impact on protecting and advancing public health.
FDA's Science Forum offers an exciting opportunity for the public to view the unique scientific research and collaborative efforts of FDA’s scientists, who speak about the critical contributions that FDA's regulatory science makes to product quality and safety to the public, industry, academia, patient advocates, sister agencies, and current and potential collaborators.
