About the Department

The goal of the Department of Infectious Diseases at St. Jude Children’s Research Hospital is to study devastating diseases of childhood through a comprehensive approach including basic science research, translational trials, and bedside care. 

Among the top infectious causes of death worldwide are respiratory diseases and HIV/AIDS. The Department of Infectious Diseases seeks to focus on the pathogenesis of these infections with a breadth of commitment that extends from the research bench to the bedside. Investigations take place at progressive levels: manipulation of genes is expected to lead to phenotypes in cell culture systems that can be modeled in animal studies. Therapeutic candidates in the form of antimicrobials, vaccines, or adjunctive therapies are further pursued in clinical trials in children.

Areas of Excellence


The Influenza research program at St. Jude leads the US effort against pandemic influenza and collaborates with the World Health Organization in tracking emergence of new influenza strains.


Department investigators are leading collaborative efforts to understand SARS-CoV-2 (and other coronavirus) biology, transmission, pathogenesis, and therapeutic vulnerabilities.  

Infection Defense

The Children’s Infection Defense Center seeks to eliminate the catastrophic infectious diseases of childhood through the use of vaccines and therapeutic agents whose development is based on an understanding of human immunity and microbial pathogenesis. 

Fellowship Training

The Pediatric Infectious Disease Fellowship Program prepares pediatricians for a successful career through comprehensive training in infectious diseases clinical medicine and in basic, translational and clinical research. 


At St. Jude, we're changing the way the world treats and defeats pediatric infectious diseases. In 1987, Danny Thomas declared AIDS a catastrophic disease of children. Soon after, the hospital made HIV/AIDS a research priority, and created the Pediatric AIDS Clinical Trial Unit.
