2021-22 CAnD3 Fellow Feinuo Sun recently published her first dissertation paper in Social Science & Medicine. This is among the first studies examining the opioid crisis in the U.S. from a spatiotemporal perspective. The paper examines how rurality impacts the prescription of opioids across U.S. counties, using a spatiotemporal dataset (2006-2018) from a variety of national data sources, such as the U.S. Opioid Dispensing Rate Maps and the American Community Survey.
