Dr. Gaggin is a general cardiologist, educator and clinical research scientist specializing in the application of biology-based science and evidence-based medicine. Her research assesses novel tools, such as biomarkers, to assess risk and evaluate risk reduction options tailored to the individual heart failure or cardiac patient. At MGH, Harvard Medical School and the Harvard Clinical Research Institute, she oversees the design and operation of clinical cardiac trials. In 2012, Dr. Gaggin received the Ruth and James Clark Fund for Cardiac Research Innovation award, an award to advance novel approaches in the evaluation and treatment of cardiovascular patients. She is currently leading a registry with a biorepository at MGH to examine heart failure with preserved ejection fraction (also commonly known as diastolic heart failure).

After receiving an MD from the Eastern Virginia Medical School, she completed her residency in Medicine at the University of Virginia and cardiology fellowship at the University of Pittsburgh Medical Center (where she served as Associate Chief Fellow for Education and the Director of the Cardiology Board Review Conference). She completed an MPH with a concentration in Quantitative Methods at the Harvard School of Public Health to focus on evidence-based research methods and clinical care.

In addition, Dr. Gaggin has provided wide-ranging cardiac care and quality education material for physicians and patients. She is the co-editor of the MGH Cardiology Board Review book, which featured the expertise of over 70 faculty members and fellows. In addition, she has authored numerous review articles and book chapter for high-tier journals and preeminent textbooks.
