I am originally from the United Kingdom and completed medical school and internship at Imperial College, London, before moving to Boston, Massachusetts in 2006. After internal medicine residency at Boston University Medical Center and a chief resident year, I moved to Cleveland Clinic, Ohio, for specialty training in cardiology. I completed an additional year of advanced heart failure and transplant cardiology training. I spent a decade on staff at Tufts Medical Center in Boston, where I led the Heart Transplant Program and latterly the Advanced Heart Failure Program, and developed a Nutrition-Heart Failure research program. My research interests are based around the interactions between nutrition, metabolism and body composition for patients with heart failure. My earlier research work was focused on the relationship between obesity and heart disease, including the impact of bariatric surgery on cardiovascular health. My current work, which is funded by the National Institutes of Health, is investigating whether dietary protein supplementation can reverse skeletal muscle wasting, as well as biological mechanisms that may contribute to cachexia development and ultrasound as a technique to assess and monitor muscle wasting in the arms and legs. Clinically, I mostly see patients with advanced heart failure and transplantation, including patients with sarcoidosis and other cardiomyopathies. I am a Diplomate of the American Board of Obesity Medicine and medically treat obesity in patients with heart failure with preserved or reduced ejection fraction. As of March 2024, I have returned to Cleveland Clinic Ohio to serve as the Section Head of Heart Failure and Transplantation Cardiology.
