About Tomas Neilan, MD, MPH

Dr. Neilan received his M.D. from University College Dublin and MPH from Harvard School of Public Health. He completed internal medicine residency and cardiology training at the Mater Misericordiae Hospital in Dublin and again at Massachusetts General Hospital. He has also completed extensive training in echocardiography at Massachusetts General Hospital and cardiac magnetic resonance at the Brigham and Women's Hospital. Dr. Neilan is an Associate Professor of Medicine at Harvard Medical School, the Director of the Cardio-Oncology Program and the Co-Director of the Cardiac MR PET CT Program.

Dr. Neilan has had a long-standing clinical and research interest in the cardiovascular care of patients with cancer. Cardiovascular disease is a leading cause of death and disability among cancer survivors and cardiovascular care for patients with cancer requires a tailored approach that is unique for each patient. He is specifically interested in how we can improve on the methods for detection of the cardiac toxicity after chemotherapy and radiotherapy and to use that information to determine how we care for patients.
