Mathematica Expands Leadership Team to Guide Company Through Future Challenges and Toward New Opportunities

Jan 27, 2021

As we enter 2021, Mathematica is pleased to announce a series of leadership appointments as it seeks to shape an equitable and just world where evidence drives decisions to achieve global impact. These changes reflect Mathematica’s commitment to expanding its deep bench of experts in diversity, equity, and inclusion; education; children, youth, and families; international development; climate change; digital technology; and cybersecurity.

Jill Constantine is the new general manager of Mathematica’s Human Services business unit. Approaching her 20th year with Mathematica, Constantine previously served as senior vice president and director of the unit’s Education and Employment Division. She is an economist with a long-held interest in education research. Her work has focused on diversifying and expanding the teacher pipeline, training and compensating teachers, and supporting college access for Black and Latinx students experiencing poverty.

Debbie Reed takes over as director of the Education and Employment Division. Reed joined Mathematica in 2009 and has served as the general manager of the Human Services Unit for the past seven years. She oversaw growth in Mathematica’s policy analysis and program improvement practices, while the unit partnered more closely with philanthropies and government agencies at the federal, state, and local levels. An economist by training, Reed will return to partnering directly with clients to address issues focused on employment, human capital, registered apprenticeships, poverty, and inequality.

Hillary Lewis joins Mathematica as its first chief information security officer. Lewis will lead Mathematica’s digital trust strategy, which entails embedding information governance, security, and ethics into the company’s digital transformation initiatives. Before joining Mathematica, Lewis oversaw information security program maturity at Freddie Mac and led information assurance at the Office of Inspector General for the U.S. Department of Health and Human Services. She has a J.D. from the University of Houston Law Center and an M.B.A. in cybersecurity from George Washington University’s School of Business.

“From the pandemic, to the economic downturn, to protests against injustice, to cyber hacks of federal agencies and some of the nation’s largest companies, events from the past year have taught us that to fulfill Mathematica’s mission of improving public well-being, we must continue to expand breadth of expertise and lived experiences at Mathematica,” said Paul Decker, president and chief executive officer of Mathematica. “Today’s announcement is part of an ongoing effort at Mathematica to recruit staff who blend the most advanced research methods and technology with a clear-eyed and empathetic understanding of the health and social challenges facing individuals and families in the United States and abroad.”
