About Valerie

Valerie Cheh is an expert in designing and managing studies aimed at improving patient safety, long-term care, and home-based care for people with disabilities and the elderly.

Currently, she directs the Evaluation of the Independence at Home (IAH) Demonstration, for the Center for Medicare & Medicaid Innovation, an initiative that provides nurse practitioner or physician led team-based primary care in a patient’s home. She is also playing a key role in the Partnership for Patient’s evaluation, a patient safety initiative that aims to reduce inpatient harm by 40 percent.

Cheh has contributed to other important studies on improving care for the elderly and fostering employment for people with disabilities. She directed a study to monitor the implementation and effectiveness of the Ticket to Work and Work Incentives Improvement Act, including the Medicaid Infrastructure Grant and Medicaid Buy-In (MBI) programs. This research identified ways to improve Medicaid and Medicare data, looked at methods to improve research on people with disabilities, and documented progress made by the state MBI programs.

Prior to joining Mathematica, Cheh served as a senior economist at Abt Associates and an analyst at Washington University. Widely published, she also serves as a referee for professional journals, including Health Care Financing Review and Annals of Internal Medicine. She holds a Ph.D. in economics from Washington University.
