Aaron Aguirre, M.D., PhD is a physician-scientist and an attending cardiologist at the Massachusetts General Hospital and an Assistant Professor of Medicine at Harvard Medical School. Aaron received his M.D. from Harvard Medical School and his Ph.D. in electrical and biomedical engineering from the Massachusetts Institute of Technology, where he worked with Prof. James Fujimoto on high resolution optical coherence tomography methods. He then did residency and fellowship training at the Brigham and Women’s Hospital before completing a postdoctoral research fellowship in cardiovascular imaging at the MGH Center for Systems Biology with Prof. Ralph Weissleder. Dr. Aguirre's laboratory at MGH is now part of the Wellman Center for Photomedicine and the Center for Systems Biology and is closely affiliated with the MGH Cardiovascular Research Center. As a critical care cardiologist in the MGH Heart Center Intensive Care Unit, his clinical practice involves care of medical and surgical patients with all forms of advanced heart disease. He has particular interest in the area of acute decompensated heart failure and the use of mechanical circulatory support devices.

My laboratory is both at the Center for Systems Biology at MGH and the Wellman Center for Photomedicine. We are also closely affiliated with the MGH Cardiovascular Research Center. We both develop and apply innovative molecular imaging and advanced microscopy technologies to investigate the pathophysiology of myocardial infarction, heart failure, and circulatory shock. We have pioneered the use of cardiac intravital microscopy to study the beating heart at cellular resolution in animal models and have explored multiple applications of this technology.
