His work has been funded by the National Institutes of Health and published in journals including Annals of Emergency Medicine, Nature Biomedical Engineering, and Nature Machine Intelligence.
Dr. Leon Jia is an attending emergency physician at Beth Israel Deaconess Medical Center and a fellow in Emergency Department Operations through BIDMC and Harvard Medical School. His interests focus on the operational and clinical applications of AI in acute care settings, with particular attention to workflow integration and quality improvement.
Dr. Lee is an emergency physician and electrical engineer working at the intersection of clinical medicine and engineering. He majored in electrical engineering at Cornell University and worked as an integrated circuit designer at Advanced Micro Devices before earning his MS and PhD in electrical engineering at MIT, where he focused on developing innovative medical devices. He received his MD from the University of Chicago and completed his emergency medicine residency at Beth Israel Deaconess Medical Center. He is currently a clinical instructor at Harvard Medical School and a research fellow with the Center for Resuscitation Science at BIDMC. His research focuses on improving the monitoring and care of critically ill patients with the use of artificial intelligence and machine learning techniques..
Sydney Mulqueen, MD is an emergency physician at Beth Israel Deaconess Medical Center currently completing a fellowship in Geriatric Emergency Medicine. Her research centers on the intersection of artificial intelligence, geriatric emergency care, and serious illness communication. She is particularly interested in developing AI technologies to improve goals-of-care conversations, advance care planning, and value-concordant care for older adults in the acute care setting.
Dr. Jossie Carreras Tartak, MD was born and raised in Guaynabo, Puerto Rico. She completed her undergraduate studies in New York University, medical school at the University of Pennsylvania where she also earned her MBA at The Wharton School, and trained at the Harvard Affiliated Emergency Medicine Residency at Massachusetts General Hospital and Brigham & Women’s Hospital. As a faculty member at Beth Israel Deaconess Medical Center, her research has focused on leveraging large language models to improve language equity. With Dr. Haimovich, she launched a pilot to provide Spanish-preferring patients with translations of their discharge instructions generated using Claude, with plans to expand into other languages in the near future.
