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 disease, dyspnea and exercise intolerance, medical simulation, and point-of-care ultrasound. Dr. Alba’s research focuses on mechanisms of pulmonary vascular disease, specifically how platelet-endothelial cell interactions may lead to chronic thromboembolic pulmonary hypertension, and the optimal use of ultrasonography and medical simulation to enhance procedural training for internal medicine residents and critical care fellows. 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.
