研究领域

Cell biology and molecular physiology of the heart and muscle. We study the cardiac, skeletal, and vascular muscle under normal conditions, during pathological conditions such as myocardial infarction, heart failure, and cardiac myopathies, and after exercise training in both health and disease. This includes studying the cellular and molecular mechanistic events that underlie and translate into improved function and clinical outcome in health and disease, with the use of experimental exercise and disease models and biophysical, biochemical, molecular, physiology, and pharmacological methods
