Associate Professor
Dr. Zègre-Hemsey is an associate professor with expertise in emergency cardiac care. Her research is focused on improving outcomes for individuals with acute coronary syndrome (ACS), and other time-sensitive cardiovascular conditions.
In her current research, Dr. Zègre-Hemsey investigates (1) cardiac monitoring (electrocardiography) and other non-invasive physiological measures, and (2) implementation of evidence-based innovations into prehospital and acute care settings, to advance patient triage, diagnosis, and access to care.
Dr. Zègre-Hemsey is an emergency department nurse with a PhD in Nursing from the University of California, San Francisco (UCSF). She is also an adult-gerontology clinical nurse specialist (CNS) with a focus on critical-care trauma. Dr. Zègre-Hemsey holds an adjunct faculty appointment in the UNC School of Medicine, Department of Emergency Medicine.
