Dr. Ellinor was raised in Cincinnati and graduated summa cum laude from the University of Cincinnati with a degree in Biology.  He attended Stanford University for medical and graduate school.  After completing doctoral work in the laboratory of Dr. Richard Tsien, he moved to Boston for medical residency at Brigham and Women’s Hospital.  He then completed cardiology and cardiac electrophysiology fellowship training at Massachusetts General Hospital.  Dr. Ellinor joined the staff of MGH in 2001, served as the Medical Director of the Cardiac Step-Down Unit for thirteen years, and recently became the Director of the Cardiac Arrhythmia Service.  He is a Professor of Medicine at Harvard Medical School and an Associate Member at the Broad Institute.

Dr. Ellinor’s research work has focused on identifying the molecular basis of atrial fibrillation. His research laboratories are located in the Cardiovascular Research Center at MGH and at the Broad Institute of Harvard and MIT.  Dr. Ellinor currently helps to lead the AFGen Consortium, an international group of investigators studying the genetics of atrial fibrillation. Over the past 15 years, he has been continuously funded by the NIH, he has received an Established Investigator Award from the AHA, and he is a principal investigator on a Transatlantic Research Network sponsored by the Fondation Leducq. Dr. Ellinor is a member of the American Heart Association, the Heart Rhythm Society and the American Society of Clinical Investigation.

Research & Publications

Research Summary
The goal of Dr. Ellinor's laboratory work is to use genetics to elucidate the molecular basis underlying abnormalities of the heart rhythm and heart function. Much of his recent work has focused atrial fibrillation which is the most common arrhythmia. To identify novel pathways for atrial fibrillation he has used a broad range of techniques including population genetics, electrophysiology, and animal models of arrhythmias.
