Dr. Sanjay Kumar Jain is a Professor of Pediatrics, Radiology and Radiological Science. He is also a Professor of International Health at the Bloomberg School of Public Health. His areas of clinical expertise include infectious diseases and international health and pediatric infectious disease.

Dr. Jain serves as the director of the Center for Infection and Inflammation Imaging Research.

Born in Halifax, Canada, Dr. Jain grew up in India. He received his medical degree in 1999 from All India Institute of Medical Sciences in New Delhi, where he was a house officer in neuroradiology. He trained in pediatrics at Penn State Children’s Hospital, Milton S. Hershey Medical Center, and the Tufts University School of Medicine. He was a clinical fellow in pediatric infectious diseases at Johns Hopkins before joining its faculty in 2005. Dr. Jain was named an associate professor of pediatrics in the Division of Pediatric Infectious Diseases in 2011.

The focus of Dr. Jain’s research is to find new and better ways to combat tuberculosis (TB). To this end, his research focuses on the development and use of imaging technologies to study TB pathogenesis and as tools for monitoring disease. He also studies the pathogenesis of CNS TB and utilization of new diagnostics for childhood TB. In the Center for TB Research at Johns Hopkins, he and his research colleagues received a 2007 $1 million Bill & Melinda Gates Foundation award to design a system that visually tracks the behavior of M. tuberculosis in the body with the goal of developing faster, cheaper drug therapies against a disease that affects billions around the world. 

Dr. Jain is an organizing member of the TB Drug Accelerator Meeting for the Bill & Melinda Gates Foundation. He has been recognized with several awards, including $2.2 million in funding through a Transformative Research Award from the National Institutes of Health and a NIH Director’s New Innovator Award in 2009. more

Research & Publications

Research Summary

Dr. Jain’s primary research interests include the development of imaging technology for real-time evaluation of M. tuberculosis infection and pathogenesis of central nervous system (CNS) tuberculosis. He has developed both in vitro and in vivo murine models to study CNS invasion by M. tuberculosis.

As part of a Gates Foundation-funded project, Dr. Jain is developing imaging technologies to evaluate M. tuberculosis infections in real-time. These include CT and PET imaging to evaluate the anatomic and inflammatory state of lungs of animals experimentally infected with M. tuberculosis. Using novel radio-nucleotide imaging technology, Dr. Jain is also developing technologies to image live mycobacteria using SPECT imaging. He is also leading a study to evaluate a novel TB test for the diagnosis of active TB in young HIV-infected children in India.
