Dr. Emeruwa is an Assistant Clinical Professor in the Division of Pulmonary, Critical Care, and Sleep Medicine at the David Geffen School of Medicine at UCLA. His clinical focus is critical care, particularly the use of extracorporeal membrane oxygenation (ECMO) for management of severe acute respiratory distress syndrome (ARDS). His research interests center around resource allocation and innovation in critical care. His doctoral dissertation, entitled "Critical Care in a Healthcare Crisis: Using Reliability and Microsimulation Methods to Understand Implications of a Proposed Resource Allocation Policy," examined the potential impact of the University of California's published triage allocation policy on ICU mortality and racial disparities in critical care resource allocation. He is an inaugural alumnus of the UCLA Biodesign Innovation Fellowship Program, through which he has worked with a team of clinicians and engineers to develop novel technologies in neurocritical care. 

Dr. Emeruwa is board-certified in pulmonary disease, critical care medicine, and internal medicine by the American Board of Internal Medicine (ABIM). He completed his internal medicine residency and chief residency at New York-Presbyterian Hospital/Columbia University Irving Medical Center (NYP/CUIMC). He earned his MD from the Columbia University College of Physicians and Surgeons, his MBA from Columbia Business School, and his PhD from the UCLA Fielding School of Public Health. Before entering medicine, he earned his bachelor’s degree in biomedical sciences and engineering from Harvard University. He was born and raised in southern California and is an avid fan of Lakers basketball and Marvel/DC comics.
