How I am inventing the future of medicine
With the use of magnetic resonance imaging (MRI) in combination with other imaging modalities, we study atherosclerotic lesions in order to determine the mechanisms underlying their development and progression. We develop hypotheses through the methods we develop and test them against histological and other clinical evidence in order to come up with more accurate studies that will determine, with greater accuracy, the risks and other factors to prevent stroke, atherosclerosis and other coronary events or even predict them before they can occur.
Research Interests
Magnetic resonance imaging
Multi modal imaging techniques
Vulnerable carotid plaque
High risk plaque
Intraplaque hemorrhage
Atherosclerosis
Stroke
Coronary events
Cardiovascular disease

Research Description
I have pioneered multiple high-resolution MRI techniques and the many image analysis tools that have been developed in our laboratory to detect vulnerable atherosclerotic plaques and led numerous MRI studies examining carotid atherosclerosis for risk stratification in patients with prior ischemic symptoms and known lesions of atherosclerosis. My research focus is on the discovery of several key plaque features associated with current and future clinical symptoms; intraplaque hemorrhage, lipid-rich necrotic core, and luminal ulceration (and/or disruption), as well as an MR technique to examine plaque neovasculature and inflammation; the role carotid intraplaque hemorrhage plays in stroke and ultimately to lead to better clinical management of atherosclerotic patients.

My expertise has also been used to assist in the development of an innovative educational program that will take advantage of advancements in hybrid clinical imaging (PET/CT, SPECT/CT, PET/MRI) that may also be useful in other fields through training of individuals and designing imaging-based trials and supervising imaging- based studies and clinical trials.
