Biography:

Arlene Ash, PhD, is Professor and Division Chief for Biostatistics and Health Services Research in the Department of Quantitative Health Services at the University of Massachusetts Medical School, and an internationally recognized methods expert in health services research. She pioneered tools for using administrative data to monitor and manage health care delivery systems, including those now used by the US Medicare program. In 1996, she co-founded DxCG, Inc. (now Verscend) to promote “fair and efficient health care” via predictive software, and received AcademyHealth’s 2008 HSR Impact Award (“Risk-Based Predictive Modeling”). She was one of 6 appointees to the COPSS-CMS white paper project: “Statistical Issues in Assessing Hospital Performance.” Her UMass team has helped MassHealth incorporate social determinants of health into Medicaid/CHIP global payments. Her ~200 research publications reflect long-standing interests in gender, age, and racial disparities; and quality, equity, and efficiency in health care financing and delivery.
