Biography
Erica Leifheit is a Research Scientist in the Department of Chronic Disease Epidemiology at Yale School of Public Health. Her research interests are in cardiovascular and cerebrovascular disease epidemiology and outcomes. Dr. Leifheit’s earlier work focused on the relationship of psychosocial factors, such as social support, depression, and stress, to patient-centered outcomes and adherence after acute myocardial infarction. Her current work centers on outcomes after stroke, using national healthcare claims data to better understand patterns in stroke care delivery and outcomes across hospitals and geographic regions. She is also involved in a number of projects that use Medicare administrative data to enhance the surveillance of patient outcomes for clinical trials and prospective registries. Dr. Leifheit received her PhD in epidemiology and public health from Yale University.
