Pediatric Infectious Diseases


Chandy C. John, M.D., M.S., holds the Ryan White Endowed Chair in Pediatric Infectious Disease and is director of the Ryan White Center for Pediatric Infectious Disease and Global Health at Indiana University. Dr. John joined the faculty at Indiana University in 2015, after serving as director of the Division of Global Pediatrics at the University of Minnesota for 10 years. Dr. John’s research focuses on malaria pathogenesis, immunology and epidemiology. Key discoveries of his collaborative research team include: 1) the first prospective studies to establish that severe malaria is associated with long-term cognitive impairment in children, 2) identification of immunologic factors that increase risk of severe malaria and cognitive impairment after severe malaria; and 3) determination of geographic and immunologic factors that affect risk of malaria in areas of unstable malaria transmission.

He conducts research and training in Kenya in collaboration with colleagues at the Kenya Medical Research Institute and Moi University, and in Uganda in collaboration with colleagues at Makerere University. He is the author of more than 130 peer-reviewed publications and 30 book chapters. Dr. John serves on the Thrasher Research Fund Scientific Advisory Committee, and has served on or chaired numerous NIH and national and international study sections and review boards. Dr. John’s awards include the Pediatric Infectious Diseases Young Investigator Award (2004), and the Bailey K. Ashford Medal from the American Society of Tropical Medicine and Hygiene for contributions to tropical medicine research (2011).

Dr. John is an active clinician, specializing in pediatric infectious diseases, tropical medicine and travel medicine. As an educator, Dr. John was co-director of global health residency tracks in pediatrics at Case Western Reserve University and the University of Minnesota, and served as co-director of the Morris Green Physician-Scientist Training Program for pediatrics and medicine-pediatrics residents at Indiana University. Dr. John is also an author of essays, poetry and fiction.

Riley Hospital for Children, Indianapolis 


Dr. John’s lab investigates malaria immunoepidemiology, the pathogenesis of severe malaria, and interactions between malaria and other disease states like iron deficiency and sickle cell disease.

The John Lab is a collaborative research group that conducts research at Indiana University and in Uganda (with Makerere University) and Kenya (with the Kenya Medical Research Institute and Maseno University).

The John Lab focuses on six major research questions:
1. Which host and pathogen factors contribute to development of severe malaria?
2. How does the immune response contribute to neurodevelopmental impairment in children with severe malaria?
3. How can iron deficiency be safely treated in malaria endemic areas?
4. What contributes to the increased risk of death from malaria in children with sickle cell disease?
5. How do changing transmission conditions affect development of immunity in malaria?
6. What causes malaria to persist in low transmission settings, and how might it be eliminated?


1. NIH/NINDS R01 NS055349 (PI: John, CC)
Neurodevelopmental outcomes in severe malaria
The major goal of this project is to assess whether the most common forms of severe malaria all lead to neurodevelopmental impairment, and if so, by which pathways they do this.

2. NIH/NINDS/FIC D43 NS078280 (PI: John, CC)
Research training in infection and neurodevelopment in Uganda
The major goal of this project is to train Ugandan Masters and doctoral students and post-doctoral fellows in the areas of infection and neurodevelopment.

3. Doris Duke Foundation ICRA 2013139 (PI: John, CC)
9/1/13 – 8/31/16
Novel Use of Hydroxyurea in an African Region with Malaria
The major goal of this project is to determine the incidence of malaria in children with sickle cell anemia treated with hydroxyurea vs. placebo.

4. Doris Duke Foundation DDCF 2015053 (PI: John, CC)
Clinical Research Mentorship: Iron deficiency in sickle cell anemia.
The major goal of this project is to provide training for a medical student in sickle cell disease and iron deficiency.

5. Research Council of Norway ES529474 (PI: Phiri, K)
Malaria Chemoprevention for the post-discharge management of severe anemia in children in Malawi, Uganda and Kenya: Moving towards policy
Role: Co-investigator
The major goal of this project is to determine if malaria chemoprovention for a 3-month period decreases rates of readmission and death in children with severe anemia.

6. NIH/NICHD 1R01HD086124 (PIs: John, CC; Bangirana, P)
Prophylaxis against malaria to enhance child development
Role: Principal Investigator
The major goal of this project is to determine the effect of malaria prevention in pregnant women and their children on child neurodevelopment, and to identify the major mechanisms through which this malaria prevention affects child neurodevelopment.
