Dr. Diana Epstein is a prominent American policy researcher and federal official currently serving as the Evidence Team Lead at the Office of Management and Budget (OMB). As of 2026, she is widely recognized as a central figure in the implementation of the Foundations for Evidence-Based Policymaking Act of 2018, specializing in federal evaluation standards and agency capacity building.
Establishing the Identity of Diana Epstein
Given the prominence of the Epstein name in various public contexts, it is essential to distinguish the subject of this professional profile from other figures. The primary search intent for "Diana Epstein" in a professional and technical capacity refers to Dr. Diana Epstein, a leading expert in evidence-based policymaking. While there are historical figures in the arts—such as the late casting director Diana Epstein (known for The Godfather Part II) and the late boutique owner and button expert Diana Epstein (founder of Tender Buttons)—the current technical and governmental focus belongs to the OMB senior official.
Dr. Epstein’s career has been defined by a commitment to using rigorous data and evaluation to improve the efficiency and effectiveness of government programs. Her background spans elite academic training in policy analysis and high-level service across several federal agencies, making her a "Subject Matter Expert" (SME) in how the United States government measures its own success.
Academic Background and Professional Foundation
The background of Dr. Diana Epstein is rooted in a rigorous multi-disciplinary education. She began her academic journey at Brown University, where she earned a Bachelor of Science in Physics. This foundation in hard science likely informed her later approach to policy—prioritizing empirical evidence, systematic testing, and reproducible results.
Following her undergraduate studies, she moved toward the intersection of science and governance, earning a Master’s degree in Science and Technology Policy from the Georgia Institute of Technology. This transition signaled an interest in how technical expertise can be translated into actionable public policy.
The "key detail" of her academic pedigree is her Ph.D. in Policy Analysis from the Pardee RAND Graduate School, one of the most prestigious institutions for policy research in the world. Her doctoral work, particularly her dissertation titled "The Impact of Charter Schools on Student Achievement: A Meta-Analysis," demonstrated her early mastery of complex data synthesis. This work remains a cited resource for understanding how meta-analytical techniques can be applied to contentious educational debates.
Career Progression: From Research to Federal Leadership
Before her current role at the OMB, Dr. Epstein developed her expertise at several critical organizations:
- Mathematica Policy Research: As a senior researcher, she worked on the "front lines" of program evaluation. Mathematica is known for conducting high-stakes evaluations for government agencies, and her time there provided her with a deep understanding of the technical challenges involved in large-scale data collection and analysis.
- Corporation for National and Community Service (CNCS): Now known as AmeriCorps, this was where Dr. Epstein took on significant federal leadership. Serving as the Evaluation Officer, she was responsible for overseeing the research and evaluation of national service programs. At CNCS, she was instrumental in building an "evidence culture," ensuring that taxpayer dollars were being funneled into programs with proven track records of success.
- Office of Management and Budget (OMB): Transitioning to the OMB placed her at the nerve center of the Executive Branch. As the Evidence Team Lead within the Office of the Director, she moved from evaluating single programs to shaping the evaluation framework for the entire federal government.
Key Details of the Foundations for Evidence-Based Policymaking Act
A significant portion of Dr. Epstein's work in recent years has focused on the implementation of the Foundations for Evidence-Based Policymaking Act of 2018 (often referred to simply as the Evidence Act). By 2026, the long-term impacts of this legislation have become clear, largely due to the guidance documents and standards produced by her team at the OMB.
The Role of Learning Agendas
One of the core requirements of the Evidence Act is for federal agencies to create "Learning Agendas" (multi-year evidence-building plans). Dr. Epstein has been a key architect in defining what these agendas should look like. A Learning Agenda is not merely a list of questions; it is a strategic document that identifies the most critical information gaps an agency faces and outlines how it will use research to fill them.
Capacity Assessments
Dr. Epstein has also led the push for "Capacity Assessments." These are technical audits of an agency's ability to conduct and use research. By 2026, these assessments have become standardized across the federal landscape, ensuring that agencies have the staff, data infrastructure, and leadership support necessary to fulfill their statutory requirements under the Evidence Act.
Technical Depth: Federal Evaluation Standards and Circular A-11
To understand the "technical depth" of Diana Epstein’s work, one must look at OMB Circular A-11. This is the primary document that guides how federal agencies prepare and submit their budget requests. Under Dr. Epstein’s influence, Circular A-11 has been revised to more tightly integrate evidence into the budget process.
In the current 2026 fiscal environment, agencies are expected to provide "Evidence Checklists" or "Evidence Evidence" alongside their funding requests. This technical requirement ensures that programs with strong evaluative backing are prioritized for funding, while those lacking data are subjected to more rigorous scrutiny or "demonstration" phases.
Standards of Excellence
Dr. Epstein has advocated for a "Standards of Excellence" framework for federal evaluations. This includes:
- Independence: Ensuring that evaluators are insulated from political pressure.
- Transparency: Requiring that evaluation plans and results be made public, regardless of whether the findings are positive or negative.
- Rigorous Methodology: Favoring randomized controlled trials (RCTs) and quasi-experimental designs where appropriate, while acknowledging the value of qualitative data in understanding implementation.

The Impact of Dr. Epstein's Work on the 2026 Federal Landscape
As we navigate the fiscal and social challenges of 2026, the "Epstein-led" approach to governance has become the standard operating procedure. The shift from "opinion-based" to "evidence-based" policy has several practical implications for the public and for stakeholders:
- Increased Accountability: It is significantly harder for federal programs to persist without data proving their utility.
- Data Accessibility: Through the implementation of the Open Government Data Act (a component of the Evidence Act), more federal data is available in machine-readable formats for researchers and the public.
- Efficiency in Spending: By identifying "what works" through the meta-analysis techniques Dr. Epstein perfected early in her career, the government can prune ineffective programs and scale successful ones.
