About George Alba, MD

Dr. Alba studied English Literature and Biology as an undergraduate at Washington University in St. Louis, earned his MD at the Mount Sinai School of Medicine, and then completed both Internal Medicine and Pulmonary and Critical Care Medicine training at Massachusetts General Hospital (MGH). As an Instructor of Medicine at Harvard Medical School and Pulmonary and Critical Care Physician at MGH, Dr. Alba is actively engaged in clinical care, research, and teaching. Dr. Alba’s clinical interests include general pulmonary and critical care, pulmonary vascular diseases, dyspnea and exercise intolerance, and long-term recovery from COVID-19. Dr. Alba’s research focuses on mechanisms of pulmonary vascular disease, specifically how hypoxic endothelial dysfunction regulates platelet-endothelial cell interactions, and the relevance to long-term outcomes from hypoxemic respiratory failure, including COVID-19. As Associate Director of the Coronavirus Recovery (CORE) clinic, Dr. Alba is helping to care for and study the acute and chronic consequences of COVID-19. As an educator, Dr. Alba enjoys teaching and training medical students, residents, and fellows in the Medical Intensive Care Unit, teaches pulmonary physiology at Harvard Medical School, and is the recipient of accomplished teaching citations and a patient safety star related to efforts in quality improvement.

Dr. Alba conducts basic and translational research in pulmonary vascular disease with the goal of identifying novel therapeutic targets and treatment modalities. The current work is focused on how local hypoxia results in endothelial dysfunction to affect platelet-endothelial cell interactions in the pulmonary circulation in a host of pulmonary disorders, ranging from chronic thromboembolic pulmonary hypertension to acute respiratory distress syndrome, including COVID-19.  He is a recipient of the MGH Center for Diversity and Inclusion Physician-Scientist Development Award and the Harvard KL2/Catalyst Medical Research Investigator Training Award.
