Dr. Daniel Bruce Ennis stands as a distinguished Professor of Radiology at Stanford University with over twenty years of impactful contributions to medical imaging science. His academic journey began with doctoral studies in Biomedical Engineering at Johns Hopkins University, where he established a productive collaboration with the Laboratory of Cardiac Energetics at the National Heart, Lung, and Blood Institute. Following his PhD, he joined Stanford University as a postdoc across Departments of Radiological Sciences and Cardiothoracic Surgery, establishing an independent research program with an NIH K99/R00 award. Dr. Ennis subsequently led a research group at UCLA for ten years before returning to Stanford in 2018 to bolster cardiovascular MRI programs, while also serving as Director of Radiology Research for the Veterans Administration Palo Alto Health Care System.
Dr. Ennis has pioneered advanced translational cardiovascular MRI methods that enable quantitative assessment of cardiac structure, function, flow, and remodeling in both adult and pediatric populations. His innovative research program has generated substantial scholarly impact with over 5,600 citations, reflecting the significance of his contributions to medical imaging methodologies. His work on myocardial structure, function, and remodeling in conditions such as mitral regurgitation has provided critical insights into cardiac pathophysiology while developing practical imaging tools for clinical use. Recent publications in 2025 continue to advance the field, with studies addressing EPI-based distortion correction techniques for cardiac diffusion tensor imaging and characterizing myocardial stiffness through personalized MRI and finite element modeling.
Dr. Ennis has cultivated a robust collaborative environment that brings together clinicians, scientists, and engineers to tackle complex challenges in cardiovascular diagnostics. His leadership at the Veterans Administration Palo Alto Health Care System ensures that cutting-edge imaging technologies translate into improved care for veteran populations. His current research focuses on refining MRI techniques to provide more accurate, accessible, and clinically relevant assessments of cardiac health across diverse patient populations. Dr. Ennis remains dedicated to advancing cardiovascular MRI through rigorous science, collaborative innovation, and translational applications that enhance patient outcomes and clinical decision-making.
