John is professor at the Robert F. Wagner Graduate School of Public Service at New York University, and the director of the school's Health Policy and Management program. He is principal investigator of numerous projects aimed at assessing the performance of the safety net for vulnerable populations and understanding the nature and extent of barriers to optimal health for vulnerable populations.
Much of John’s work focuses on the analysis of patterns of hospital admission and emergency room visits as a mechanism to evaluate access barriers to outpatient care. His work also assesses the performance of the ambulatory care delivery system. John has examined the characteristics of high cost Medicaid patients to help in designing interventions to improve care and outcomes for these patients. Parallel work in the United Kingdom has involved creating an algorithm for the National Health Service (NHS) to identify patients at risk of future hospital admissions and designing interventions to improve care for these high-risk patients.
John holds a law degree from the University of California, Berkeley.
John joined the Healthwise Board in 2014.
