Senior Researcher

Photo of Andrew ClarkwestAndrew Clarkwest is a senior researcher with expertise in experimental and quasi-experimental policy research. His experience covers a range of policy areas, including family formation and stability, employment, and quality of health care. His work reflects a particular interest in low-income couples and families and racial and ethnic disparities in well-being and treatment.

He is currently leading the impact evaluation task of the evaluation of the Centers for Medicaid Services’ $1 billion Partnership for Patients’ (PfP) initiative, and previously directed studies conducted on behalf of the U.S. Department of Labor and the Illinois Department of Employment Security.

Clarkwest has conducted numerous studies of couple stability and well-being, including his key role in developing analytical approaches and measures for the Building Strong Families demonstration, an experimental evaluation of a relationship skills education program predominantly for low-income couples who conceived children outside of marriage.


His experience with experimental program evaluation also includes his current work designing and carrying out a randomized controlled evaluation of reemployment and training services funded through the Workforce Investment Act. His quasi-experimental design experience includes work using regression discontinuity, instrumental variables, and propensity score-based comparison group designs. He also applies his expertise in quantitative study design as a deputy principal investigator for the U.S. Department of Education’s What Works Clearinghouse.

Prior to joining Mathematica in 2007, he was a postdoctoral research fellow at the Population Studies Center at the University of Michigan. His peer-reviewed research has been published in venues including the Journal of Policy Analysis and Management, the Journal of Marriage and Family and Social Science & Medicine. He holds a master’s degree in public policy and a Ph.D. in sociology and social policy from Harvard University.
