Karen is a health economist specializing in Medicaid policy, program evaluation, and health system transformation.

Karen helps state and federal clients assess how complex health care programs are implemented, who they reach, and whether they achieve their intended goals. Her expertise includes Medicaid demonstrations, value-based payment models, behavioral health and substance use disorder programs, rural health initiatives, and health care delivery reform. Drawing on qualitative and quantitative methods, Karen designs and leads mixed-methods evaluations that generate actionable findings to inform policy, program improvement, and future investments.

At NORC, Karen leads evaluations of Medicaid Section 1115 demonstrations, rural health transformation initiatives, and other major health policy initiatives for state and federal clients. She directs multidisciplinary teams responsible for evaluation design, stakeholder engagement, quantitative and qualitative analyses, and reporting. Her recent work includes leading the Evaluation of Vermont's Rural Health Transformation Program, as well as leadership roles on evaluations in California, Minnesota, Rhode Island, and other states pursuing innovative approaches to improving access, quality, integration, and value in health care.

Karen’s work has been published in several peer-reviewed journals, including The American Journal of Managed Care, Health Services Research, and the Journal of General Internal Medicine.
