I am originally from the United Kingdom and completed medical school and internship at Imperial College, London, before moving to the USA in 2006. After internal medicine residency at Boston University Medical Center and a chief resident year, I completed specialty training in cardiology and an additional year of advanced heart failure and transplant cardiology training at Cleveland Clinic, Ohio. 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 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.
