Dr. Virani’s research portfolio aims to understand the pathophysiology and epidemiology of atherosclerosis with a special emphasis on South Asians. His team is studying several domains in the delivery of high-quality guideline concordant primary and secondary cardiovascular disease preventive care. Via funded research grants from the Department of Veterans Affairs, American Diabetes Association, American Heart Association, NIH, AHRQ, and the World Heart Federation, his team has been evaluating models of delivery of cardiovascular disease preventive care, how to leverage machine learning while using “big data”, and how point-of-care informatics driven interventions can improve guideline-concordant care delivery. His team is also evaluating how best to leverage technology to deliver high-quality care in Low-Middle Income Countries especially in South Asia. He has authored or co-authored >600 peer-reviewed publications or book chapters (several with his mentees) related to various aspects of cardiovascular disease prevention including cholesterol, blood pressure control and aspirin therapy with several in high-impact journals such as Circulation, European Heart Journal, JAMA, JAMA Cardiology, and Journal of the American College of Cardiology. This work has received >110,000 citations. He has been recognized as “World Expert” in Cholesterol by Expertscape (top 0.01% of scholars writing about cholesterol from 2011-2021 among 181,887 published authors) and among the top 2% of the most cited scientists worldwide by PLos Biology in 2022. Dr. Virani has also served as a faculty for >50 online literary educational programs and has participated in >100 online or in person media interviews.
