His primary areas of research are in nuclear, preventive and clinical cardiology. He serves, and has served, as a consultant to a number of companies developing new molecules for clinical use. His research work is reflected in over 100 articles, abstracts, book chapters and the text Exercise & Health: The Evidence and the Implications. He frequently presents his work in the US and abroad.
His major contributions in nuclear cardiology have been helping pioneer the addition of low level exercise to adenosine stress, databasing and prognostic studies of outpatient myocardial perfusion imaging, encouraging the merging of nuclear cardiology images with those of cardiac CT and developing protocols for the use of a new stress vasodilator agent, regadenoson, with low level exercise and in COPD patients.
Beginning in 2008, he has co-led a joint US-Egyptian team that discovered that ancient Egyptian mummies housed at the National Museum of Antiquities in Cairo, Egypt had atherosclerosis. This work challenges the conventional wisdom that atherosclerosis is a disease of contemporary humans.
