President and CEO Paul Decker
“Mathematica is an end-to-end partner for organizations and decision makers who want to act on the most accurate and complete information, with a commitment to equity and sustainability.”
Mathematica President and CEO Paul Decker is a nationally recognized expert in policy research, evaluation, and data analytics. With specialized expertise in education and labor policy, Paul has worked for more than three decades to improve public well-being through the use of data and evidence.
As chief executive of Mathematica since 2007, Paul has overseen the development of Mathematica as a company uniquely positioned to use data science, social science, and digital innovation to help solve pressing social challenges—from the global effects of climate change to national disparities in health, education, and employment. Under his leadership, Mathematica supports data-driven decision making for private- and public-sector organizations, providing expertise in end-to-end analytics, a deep understanding of policy context, and a strong foundation of consequential research and evaluation.
In 2018, Paul was honored as CEO Connection’s Mid-Market CEO of the Year. He has since led Mathematica to recognition as a Disability Equality Index Best Place to Work for Disability Inclusion, an HRC Equality Index Leader in LGBTQ+ Inclusion, and the National ESOP Association’s ESOP of the Year Award for the New York/New Jersey region.
Expanding our work to improve public well-being
Paul holds a Ph.D. in economics from Johns Hopkins University and serves as chair of development on the board of advisers of the Thomas Jefferson Public Policy Program at the College of William and Mary, his undergraduate alma mater. After joining Mathematica in 1988 as a researcher focused on education and labor policy, Paul served in multiple project and leadership roles before eventually being named president and CEO in 2007. Since then, he has expanded and diversified the company’s operations and maintained its commitment to rigor, objectivity, and improving public well-being by:
- Strengthening data analytics capabilities across the organization to better support effective policy and program development decisions through sophisticated data management and analytics, predictive models, and the ethical and sustainable use of artificial intelligence.
- Launching an enterprise focus on commercial health care, in which data scientists and social scientists collaborate to improve equitable and affordable access to high-quality care.
- Expanding Mathematica’s expertise and work to include behavioral insights to improve program design and new methodological strategies, such as the application of Bayesian statistical methods to social program evaluations.
- Launching Mathematica Global, which offers end-to-end measurement, evaluation, research, and learning (MERL) services to accelerate inclusive, equitable, and sustainable development.
- Completing Mathematica’s first acquisition, bringing the London- and Kenya-based EDI Group into the Mathematica family.

“We want to make sure the evidence is as useful and as informative as possible to those who are going to use it – policymakers and other decision makers.” –A conversation with Moody’s Chief Economist Mark Zandi
A past president of the Association for Public Policy Analysis and Management, Paul has co-chaired the organization’s strategic planning committee and served on its policy council. He currently edits the Point/Counterpoint column in APPAM’s quarterly journal and also writes and speaks regularly on trends in the policy research field, including the emergence of Big Data and its impact on public program evaluation and management. Paul is a Trustee of the Committee for Economic Development where he is co-chair of the subcommittee on labor force participation, and has testified before Congress, served as an expert adviser to both the U.S. and Canadian governments, and published widely in peer-reviewed journals.

Championing the power of employee ownership
“Mathematica employees not only support our clients’ and partners’ commitment to impact, we share a stake in the outcome.”
Arriving at Mathematica shortly after the company transitioned to an independent, employee-owned firm, Paul experienced how this decision helped further define Mathematica’s mission, elevated the quality of work, strengthened accountability, and enhanced the financial strength of the company. In 2005, he was part of the senior leadership team that solidified employee ownership as a fundamental principle of Mathematica by creating an Employee Stock Ownership Plan (ESOP), a retirement plan through which all employees receive shares of company stock. Today, as the CEO of one of the few employee-owned service companies of its size and an active member of the ESOP Association, Paul believes strongly in the power of employee ownership to build employee financial security and inspire people at every stage of their careers.

“As CEO, every action you take, every decision you make has an impact on people around you and you need to be conscious of that.”–A conversation with NORC President and CEO Dan Gaylin
