Working with Mathematica

Mathematica’s expertise at the intersection of data, methods, policy, and practice helps our federal partners translate big questions into insights that enrich programs, refine strategies, and enhance understanding.

Dedicated to improving public well-being, Mathematica includes more than 1,200 experts in health, education, disability, nutrition, employment, justice, and more. Through the use of OASIS Pool 2, federal agencies can gain access to our multi-disciplinary teams. These teams collaborate closely with policymakers and agency staff to not only build the evidence base, but also uncover insights that support decision making and, ultimately, contribute to better outcomes.
