Pranita Tamma, M.D., M.H.S. is an Assistant Professor of Pediatrics within the Division of Infectious Diseases and Director of the Pediatric Antimicrobial Stewardship Program at The Johns Hopkins University School of Medicine.  She is also an Assistant Professor in the Department of Epidemiology at The Johns Hopkins Bloomberg School of Public Health. 

As Director of Antimicrobial Stewardship, Dr. Tamma assists clinicians with optimizing the selection of antibiotics, developing guidelines to guide the appropriate and judicious use of antibiotics, and monitoring patient outcomes after implementation of these practices. She is the past and present recipient of federal research funding from the NIH, FDA, CDC, and AHRQ. Her research focuses on clinical outcomes related to antibiotic administration strategies in both children and adults and the incorporation of rapid diagnostics to assist with the early optimization of antibiotic therapy. 

Dr. Tamma is particularly interested in improving diagnostic and therapeutic choices for infections caused by multidrug resistant gram-negative organisms. She is a member of the Antibacterial Resistance Leadership Group (ARLG) Gram-Negative Subcommittee and the Pediatric Infectious Diseases Society (PIDS) Antimicrobial Stewardship Committee. Additionally, Dr. Tamma serves as a Voting Member of the Clinical Laboratory Standards Institute Antimicrobial Susceptibility Testing Committee and an Advisor to The Centers for Diseases Control and Prevention in their efforts to improve inpatient antibiotic prescribing. She is an editor of the Society for Healthcare Epidemiology of America (SHEA)-sponsored textbook “Practical Implementation of Antibiotic Stewardship Programs.” more
