PRINCETON, NJ—August 7, 2012—Longtime Mathematica Policy Research staff members and Princeton residents Jill Constantine and Christopher Trenholm were recently named vice presidents and appointed to the company's senior management team. Based in Mathematica's headquarters in Princeton, Constantine and Trenholm will serve as directors of human services and health research, respectively, in that office.

Since joining Mathematica in 2001, education expert Constantine has effectively directed some of the company's largest and most complex projects. She directs the What Works Clearinghouse, which assesses the quality of education studies, curricula, practices, and policies. She also directs Mathematica's evaluation of the Teacher Incentive Fund grants, a study of performance-based compensation for educators.

Trenholm, who joined Mathematica in 1997, has built a national reputation in two major fields of policy importance—covering uninsured children and teen pregnancy prevention. Trenholm also served as principal investigator for Mathematica's congressionally mandated abstinence evaluation, which won the American Evaluation Association's Outstanding Evaluation Award in 2009.

"I am delighted to announce these appointments," said Paul Decker, president and Chief Executive Officer of Mathematica. Jill and Chris possess the kind of leadership, creativity, and dedication to the integrity and quality of our work that are crucial in helping us achieve our mission of improving the public good."
