Alexandra Baker

Dr. Alexandra Baker is a clinical faculty member in the Department of Pediatrics at Harvard Medical School and an attending physician in the Emergency Department at Boston Children's Hospital. Her work bridges clinical care and research in pediatric emergency medicine, with a specialized focus on pediatric sepsis, early detection systems, and healthcare outcomes.

Education:

• B.S. in Biology, Cornell University (2008)
• M.D., Washington University School of Medicine (2014)
• Pediatrics Residency, Boston Combined Residency Program (2017)
• Pediatric Emergency Medicine Fellowship, Boston Children's Hospital (2021)
• Chief Resident, Boston Combined Residency Program

Her research centers on improving the diagnosis and management of pediatric sepsis, particularly through the use of screening algorithms and biomarkers in emergency settings. She investigates both the benefits and potential unintended consequences of early sepsis detection, including overdiagnosis and resource utilization. Her recent work also explores national mortality trends and predictors of bacteremia in children, aiming to identify gaps in care that can be addressed systemically. She has contributed to understanding emergency response frameworks during public health emergencies such as the pediatric tripledemic of 2022.

The analysis of her recent publications reveals a strong emphasis on clinical decision-making, health systems performance, and evidence-based improvements in pediatric emergency care. Her work spans diagnostic accuracy, algorithm implementation, comparative health systems, and disaster preparedness, reflecting a multidisciplinary approach grounded in real-world clinical data.
