Daniel Bruce Ennis

Daniel Ennis is a Professor in the Department of Radiology and Bioengineering (by courtesy). As an MRI scientist for nearly twenty-five years, he has worked to develop advanced basic science and translational cardiovascular MRI methods for quantitatively assessing structure, function, flow, and remodeling in both adult and pediatric populations. He began his research career as a Ph.D. student in the Department of Biomedical Engineering at Johns Hopkins University during which time he formed an active collaboration with investigators in the Laboratory of Cardiac Energetics at the National Heart, Lung, and Blood Institute (NIH/NHLBI). Thereafter, he joined the Departments of Radiological Sciences and Cardiothoracic Surgery at Stanford University as a postdoc and began to establish an independent research program with an NIH K99/R00 award focused on “Myocardial Structure, Function, and Remodeling in Mitral Regurgitation.”

For ten years he led a group of clinicians and scientists at UCLA working to develop and evaluate advanced cardiovascular MRI exams as PI of several NIH funded studies. In 2018 he returned to the Department of Radiology at Stanford University as faculty in the Radiological Sciences Lab to bolster programs in cardiovascular MRI. He was a member of the committee that founded the Biomedical Physics (BMP) PhD program in the School of Medicine and continues to serve on the Executive Committee. He is also the Director of Radiology Research for the Veterans Administration Palo Alto Health Care System where he oversees a growing radiology research program. In 2025 he became the Division Chief for the Radiological Sciences Lab, a division within the Department of Radiology and home to about 80 faculty, staff, and trainees focused on advanced medical imaging research.
