In 2013, he was elected to the American Society of Clinical Investigation (ASCI). He is the Director of Vascular Imaging at the Cardiovascular Molecular Imaging Program. His lab is interested in applying molecular imaging technology to 1) understand the evolution and therapy of inflammation in atherosclerosis though serial, high-resolution imaging and 2) develop translatable, catheter-based fluorescence technology to study vascular disease in human coronary sized arteries.
