Dr. Michael J. Blaha MD MPH (Professor of Cardiology and Epidemiology) is the Director of Clinical Research and Director of the Cardiometabolic Clinic for the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease. Clinically, he practices as a preventive cardiologist and in the interpretation of non-contrast and contrasted cardiac CT. His clinic specializes in patients with advanced subclinical atherosclerosis, and the focused use of an array of lifestyle and pharmacotherapies to mitigate that risk. Dr. Blaha has published over 550 scientific articles, with a focus on appropriate use of tests and new therapies in the prevention of atherosclerotic cardiovascular disease as a function of atherosclerosis burden. He has served as an Associate Editor for the journals Atherosclerosis and Journal of Cardiovascular Computed Tomography, Associate Editor for the Diabetes and Cardiometabolic Clinical Community for the ACC.org, and is a standing member of the Endocrinologic and Metabolic Drug Advisory Committee (EMDAC) for the FDA. He has received multiple grant awards from the National Institutes of Health, FDA, American Heart Association, Amgen Foundation, Aetna Foundation, Bayer, and Novo Nordisk. In 2018, Dr. Blaha received the Dr. Fred Brancati award at Johns Hopkins for excellence in mentoring. He has mentored over 30 trainees, many of which have gone on to hold prominent academic appointments. In 2021, Dr. Blaha was named to the Clarivate Highly Cited Researcher List, representing the top 0.1% of world’s researchers.
Jeffrey A. Brinker, M.D.

Dr. Brinker is a professor of Medicine and Radiology at the Johns Hopkins University. He obtained his MD degree Suma Cum Laude at the State University of New York Downstate Medical Center in 1970. He did post graduate training in Medicine and Cardiovascular disease at the State University of New York, the University of Louisville, and the Johns Hopkins Medical Institutions. He Joined the Hopkins faculty in 1978 where his interests have included cardiovascular imaging and intervention as well as cardiac pacemaking. Dr. Brinker is board certified in Internal Medicine, Cardiovascular Disease, and Interventional Cardiology. He has authored or co-authored over 200 peer reviewed papers and is on the editorial board of a number of specialty journals. He is a fellow of the American College of Cardiology, and the Society for Cardiac Angiography and Intervention.
Paul S. Hees, Ph.D

Dr. Hees is an engineer and physicist who joined the Hopkins faculty after completing a Research Fellowship at Massachusetts General Hospital in 1993. He attended Worcester Polytechnic Institute, and has a background in cardiac MRI, as well as imaging applications in cancer and stroke diagnosis. His recent research interests have applied imaging methods to evaluate changes in cardiac structure and function that occur with aging.
