Philosophy of Care

I want to minimize metabolic stress of surgery and enhance recovery after cardiac operations to improve overall patient outcomes and family experience at Boston Children's Hospital.


Dr. Roy trained in general surgery, Cardiac surgery, Congenital Cardiovascular and thoracic surgery and in surgical critical care. She has established herself in the field of cardiac critical care with a focus on adult congenital critical care, ECMO and mechanical circulatory support, and research in organ resuscitation for heart and lung transplantation at Massachusetts General Hospital before being recruited at Boston Children's Hospital to develop the enhanced recovery after surgery (ERAS) initiative at the Heart Center in Boston Children’s Hospital.
