Dr. John Bradley is the medical director of the Division of Infectious Diseases at Rady Children's Hospital-San Diego and a Distinguished Professor at UC San Diego School of Medicine, the highest academic rank.

He is chair of the Scientific Review Committee for a large pediatric clinical trials consortium, I-ACT, working with academic centers, the Food and Drug Administration and the health care industry to study new tests, therapies and vaccines for COVID-19. He is also on the FDA's Advisors and Consultants Staff.

For over three decades, Dr. Bradley served as chief of the Division of Infectious Diseases at Rady Children's Hospital and more recently held this role in the Department of Pediatrics of UC San Diego. He continues to serve as the Division's medical director and divides his time between clinical care, clinical research and national policy.

Dr. Bradley's clinical research has focused on investigating new and innovative therapies for bacterial and viral infections, with a specific emphasis on finding new ways to treat antibiotic-resistant infections. He is currently funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development to investigate antibiotic dosing in critically ill children at Rady Children's Hospital pediatric intensive care unit. He is also working to bring a new national clinical trials consortium to the Hospital.

Among his many accomplishments, Dr. Bradley served on the U.S. Food and Drug Administration's Anti-Infective Drug Advisory Committee and currently serves as an advisor to FDA. He collaborated with the Centers for Disease Control and Prevention to lead an American Academy of Pediatrics Clinical Report on the bioterror threat of anthrax and was selected for a federal advisory committee on national biosecurity to represent children in the creation of national policies.

He was the lead author on the first national guidelines for the treatment of pneumonia in children and is one of the members of the CDC-lead Influenza Guidelines Committee and as well as the co-chair of the new Pediatric Bone and Joint Infection Guidelines that are currently being written. Additionally, he is the editor and a co-author for "Nelson's Pediatric Antimicrobial Therapy," a book on the treatment of pediatric infections.
