Hanna Grol-Prokopczyk, PhD, is a medical sociologist and demographer. Much of her current research focuses on chronic pain: its measurement, its social distribution, and its consequences (including opioid use and mortality). She also conducts research on how surveys can best generate interpersonally and internationally comparable measures of subjective health conditions, and on U.S. counterterrorism policy. Her work has appeared in journals including Demography, Journal of Health and Social Behavior, Journal of Gerontology: Social Sciences, and PAIN. Dr. Grol-Prokopczyk is an associate professor of Sociology at the University at Buffalo, SUNY.
