Dr. John Bradley is director of the Division of Infectious Diseases at Rady Children's Hospital-San Diego and a professor and chief of the Division of Infectious Diseases at UC San Diego School of Medicine.

He completed his pediatric infectious diseases training at Stanford University in 1981.

Dr. Bradley divides his time between clinical care and clinical research. His research focuses on the development of antibacterial, antiviral and antifungal agents (with phase I, II and III clinical studies), with the goal of finding an effective therapy for both CA-MRSA invasive infections and multi-drug resistant gram-negative nosocomial infections using pharmacodynamic/pharmacokinetic computer modeling and simulation for dose optimization.

Dr. Bradley served as an active member of the U.S. Food and Drug Administration's Anti-Infectives Advisory Drug Committee and currently serves as an advisor. He is also one of the pediatric members of the IDSA/CDC Influenza Guidelines Writing Committee and PIDS/AAP Bone and Joint Infection Guidelines Writing Committee, and formerly was the chair of the PIDS /IDSA Pediatric Community Pneumonia Guidelines Writing Committee.

Additionally, he is a section editor (antimicrobial reviews) for the Pediatric Infectious Disease Journal and sits on the editorial board of the Journal of the Pediatric Infectious Diseases Society. He also edits the American Academy of Pediatrics' "Nelson's Pediatric Antimicrobial Therapy" with John Nelson.
