Dave Mader

Senior Fellow | Legislative Reform

David Mader is a nationally recognized expert in organizational performance, program integrity and enterprise risk management. He has served in executive positions in both the federal government and the private sector and most recently for a non-profit.

He spent more than thirty years as a career executive at the Internal Revenue Service and retired as the Assistant Deputy Commissioner. While at the IRS one of his focus areas was the reduction of improper payments and refund fraud. As the Senate confirmed Controller at the Office of Management and Budget as well as the acting Deputy Director for Management he focused on creating an annual action plan for all twenty four CFO Act Departments and Agencies to establish improper payment reduction plans. Also, in 2016, he initiated the mandatory requirement for all CFO Act entities to establish enterprise wide risk management programs as part of OMB Circular A-123. David also co-led, along with the Treasury Department Fiscal Assistant Secretary, the implementation of the Data Act which provided transparency into all federal spending. As a senior executive at two major consulting firms, he worked with federal agencies in developing new approaches to reducing improper payments and worked with House and Senate committee staff in exploring additional legislation.

David will support the Program Integrity Alliance in developing our legislative and advocacy agenda, including recommendations for integrity and accountability reforms.

Jetson Leder-Luis

Senior Fellow | Value for Money Initiative

Jetson Leder-Luis is a leading scholar on the economics of fraud and anti-fraud policies in the US, with a focus on federal health programs. He is an assistant professor at Boston University and a faculty research fellow at the National Bureau of Economic Research (NBER). His academic research on fraud has been published in top economics journals, including the American Economic Review and the Journal of Political Economy, and he has served as an invited keynote speaker for the American Bar Association, the National Association of Medicaid Fraud Control Units, and the National Health Care Anti-Fraud Association. Jetson’s research has been funded by the Centers for Medicare and Medicaid Services, the National Institutes of Health, and Arnold Ventures. He earned his PhD in economics from MIT in 2020, with a dissertation titled “The Economics of Fraud and Corruption.”

Jetson’s research with PIA focused on the importance of measuring value for money (V4M) of fraud prevention policies and activities. His work explored the extent to which current measurements under-value up-front regulations and controls, as well as opportunities to strengthen V4M measurement of antifraud efforts. As part of this work, Jetson examined the relationship between up-front regulations, such as pre-payment review and prior authorization, and their relative challenges and benefits in achieving cost-effective fraud prevention.

William & Mary

Capstone Partner

We partnered with William & Mary’s Raymond A. Mason School of Business through its Master’s in Business Analytics graduate capstone program. This collaboration supported our Integrity Lab’s mission to develop practical, AI-powered tools that strengthen program integrity, fraud prevention, and transparency in government. It culminated with students’ final presentations in May 2025.

Under the guidance of Dr. Tingting (Rachel) Chung, teams of graduate students expanded PIA’s curated databases by building AI-assisted tools to identify, retrieve, and organize critical integrity-related documents of federal government agencies. These included congressional budget justifications, agency financial reports, performance accountability reports, and reports published by the Congressional Research Service.

PIA worked with students to develop exploratory analyses, a data pipeline to surface relevant reports, a coverage heatmap, a searchable dataset, and a user interface. The students played a vital role in advancing our open-source efforts, including our Recommendation Spotlight.
