Dr. Morrison is a graduate of the University of Massachusetts at Amherst and the University of Massachusetts Medical School, where he obtained a combined M.D./Ph.D. in Biomedical Sciences. He trained in Internal Medicine at Yale University School of Medicine and Yale New Haven Hospital and did a Cardiovascular Medicine Fellowship at Yale University School of Medicine. In addition, Dr. Morrison received training and certifications in advanced cardiovascular imaging, including Nuclear Cardiology and Cardiac CT. Upon completion of his clinical training, he returned to the research bench and completed a postdoctoral research fellowship in vascular biology at Yale. Dr. Morrison was appointed to Assistant Professor of Medicine at Yale School of Medicine in 2014. He was appointed to Assistant Professor of Medicine at Alpert Medical School of Brown University in 2016.
Dr. Morrison has combined careers in clinical cardiovascular medicine, teaching, and vascular biology research. He maintains a strong interest in developing basic research projects that have translational impact for clinical disease. Basic science research interests include mechanisms of immune-mediate vascular remodeling focusing of areas where macrophages direct the biologic processes of arteriogenesis, vascular calcification, and pulmonary arterial hypertension. His laboratory has a number of active studies defining novel macrophage-dependent signaling mechanisms that modulate these processes, using a diverse array of techniques in molecular biology, immunobiology, small animal genetics, and vascular biology.
