Dr. Johnson is an Assistant Professor of Pediatrics in the Division of Neonatology at the Johns Hopkins University School of Medicine and is jointly appointed as an Assistant Professor at the Johns Hopkins Bloomberg School of Public Health in the Department of International Health (Global Disease Epidemiology and Control Program). She graduated from the College of William & Mary with majors in biology and international relations. Dr. Johnson is an Alpha Omega Alpha graduate of Eastern Virginia Medical School. She completed pediatric residency and a fellowship in Neonatal-Perinatal Medicine at Johns Hopkins University. Dr. Johnson joined the faculty at Johns Hopkins in 2017. Her research interests include neonatal global health and infection prevention in low-resource settings. Dr. Johnson has conducted CDC-supported research in Pune, India, describing the epidemiology of bloodstream infections in the NICU, identifying reservoirs of transmission for resistant Gram-negative bacteria for neonatal infections, and performing an interventional study to improve healthcare worker adherence to evidence-based infection prevention and control practices. She completed a Ph.D. in Clinical Investigation at the Johns Hopkins Bloomberg School of Public Health in 2020. Her thesis, “Healthcare-associated Bloodstream Infections in the Neonatal Intensive Care Unit in Pune, India: Epidemiology and Reduction of Risk”, focused on quality improvement and patient safety interventions in four Indian NICUs. She was awarded a K23 mentored career development award by the National Institutes of Health in July 2020, which will support her continued work on epidemiology of healthcare-associated bloodstream infections and infection prevention and control in the NICU in low resource settings.

Research & Publications

Research Summary

Julia Johnson’s research interests focus on neonatal infection prevention and global health. In collaboration with colleagues in the infectious disease department, she has led a multidisciplinary research team for three CDC-funded studies focused on neonatal healthcare-associated infections in low-resource settings. She is interested in the epidemiology of neonatal bloodstream infections and antimicrobial resistance, using the Comprehensive Unit-based Safety Program (CUSP) to improve health care worker adherence to best practices in infection prevention, and assessing the role of maternal colonization in transmission of pathogens to neonates. Dr. Johnson has served as a technical expert to the CDC in a landscape analysis of neonatal infection prevention in low resource settings, work supported by the Bill & Melinda Gates Foundation. To enhance her training in clinical research methodology, Dr. Johnson received her doctorate in April 2020 in clinical investigation through the Graduate Training Program in Clinical Investigation; a joint program of the Johns Hopkins University School of Medicine and the Johns Hopkins Bloomberg School of Public Health. She was recently awarded a K23 application from the NIH to support her research and career development.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
