Dr. Pranita D. Tamma is an assistant professor of pediatrics at the Johns Hopkins University School of Medicine. She specializes in infectious diseases and pediatric emergency medicine. 

Dr. Tamma is the director of the pediatric Antimicrobial Stewardship Program. She believes that although antibiotics have saved countless lives, their use is not benign. Dr. Tamma focuses on optimizing the use of antibiotics to treat infections, while also limiting their unnecessary use and the harm they can cause when used inappropriately. She assists clinicians with the selection, route, dose, interval and duration of antibiotics, developing guidelines to guide the appropriate and judicious use of antibiotics, and monitoring patient outcomes after implementation of these practices.

She earned her undergraduate and medical degrees in a combined medical program at The City College of New York and SUNY Downstate College of Medicine. She completed both a pediatrics residency and a pediatric infectious diseases fellowship at Johns Hopkins Hospital. She also holds an M.H.S. from the Johns Hopkins Bloomberg School of Public Health. She joined the Johns Hopkins faculty in 2013.

Dr. Tamma conducts research both in the pediatric and adult population. Her research focuses on clinical outcomes related to antibiotic administration strategies and the use of rapid diagnostic tools to improve antibiotic use. Dr. Tamma has a particular interest in exploring optimal therapy for infections caused by multidrug resistant gram-negative organisms.

She serves as a reviewer for publications that include The Pediatric Infectious Diseases Journal, JAMA Pediatrics, Clinical Infectious Diseases, PLOS ONE, Pediatrics and The Journal of the Pediatric Infectious Diseases Society. more
