Biography

Joshua R. Vest, PhD, MPH, FACMI, is professor of Health Policy and Management and Associate Dean for Research at the Indiana University Richard M. Fairbanks School of Public Health in Indianapolis. He also serves as interim Chief Research Officer and a research scientist in the Clem McDonald Center for Biomedical Informatics at the Regenstrief Institute. A health services researcher and former local public health practitioner, Dr. Vest studies how health information technology, health information exchange, and public health information systems can improve clinical, organizational, and population health outcomes. His work has examined the adoption, use, policy context, and impact of technologies that share patient information across organizations, including their effects on readmissions, repeat imaging, costs, and care continuity. More recently, his research has focused on measuring and using health-related social needs and social determinants of health data to support better care delivery and population health. Dr. Vest has authored more than 150 peer-reviewed publications, and his work combines diverse methodological tools and technology interventions to inform policy, health system design, and public health practice.

Current research focus

Dr. Vest is currently advancing studies on health information exchange, health information technology adoption, and how information systems can reduce hospital readmissions, improve care continuity, and integrate social determinants of health data to enhance population outcomes.
