Dr. Silvia Chiang is a clinician-researcher who works on childhood and adolescent tuberculosis. She is board cetified in Pediatric Infectious Diseases and General Pediatrics, and attends on the pediatric infectious disease service and the TB Clinic at Hasbro Children's Hospital.
After graduating from Stanford University, Dr. Chiang served as a Peace Corps community health volunteer in rural Peru. She then returned to the U.S. and attended medical school at Case Western Reserve University. In 2012, during her last year of pediatrics residency in Boston, she returned to Peru to work with Socios En Salud (Partners In Health-Peru) on tuberculosis research. She continued her collaboration with Socios En Salud throughout her pediatric infectious diseases fellowship, which she completed at Baylor College of Medicine and Texas Children's Hospital, home to the largest pediatric tuberculosis clinic in the U.S.
Dr. Chiang currently has an NIH and foundation grants to conduct adolescent tuberculosis research in Peru. She has additional ongoing research collaborations on pediatric tuberculosis in Ukraine and Brazil.
During the COVID-19 pandemic, Dr. Chiang and Dr. Sabina Holland established a pediatric COVID telehealth clinic and have been collaborating on related research. Dr. Chiang has been interviewed about COVID-19 by The New York Times, The Boston Globe, Scientific American, The Associated Press, and other media outlets.
With Dr. Delma-Jean Watts, Dr. Chiang co-directs the Global Health Scholarly Concentration at Alpert Medical School.

I am a junior clinician-investigator who practices pediatric infectious diseases and studies childhood and adolescent tuberculosis (TB). My overarching goal as an investigator is to conduct epidemiologic and clinical research that will improve outcomes for children and adolescents with TB. Most of my research takes place in Lima, Peru, where I work with Partners In Health-Peru (PIH-Peru), a non-governmental organization that aims to improve the health of vulnerable populations through healthcare delivery and research. I have worked with PIH-Peru on five TB studies, which have led to multiple publications. One of these publications shows that weight gain early in therapy predicts treatment success in children and adolescents with TB. Another publication identifies risk factors for treatment failure and death in pediatric multidrug-resistant (MDR) TB, and suggests targets for intervention to improve outcomes. I have also published qualitative studies that evaluate barriers to childhood TB diagnosis and treatment.
In 2017, I began collaborating on pediatric TB work in Ukraine with colleagues at Bogomolets National Medical University and the Center for Public Health of the Ministry of Health. Together we have published a paper on the treatment of children with MDR-TB and another on the clinical manifestations and epidemiology TB disease in nearly 2500 adolescents.
As a junior clinician-investigator, I am working towards research independence and developing expertise in adolescent TB. Few disaggregated data exist for adolescents with TB, and their needs have been neglected in TB research and policy. To achieve my career goals, I have obtained a K01 International Research Scientist Development Award (IRSDA), which is funding my study “Teens on TB Treatment.” This study, which will continue through late 2021, uses in-depth interviews and quantitative data from a prospective cohort (n=250) to evaluate barriers and facilitators to treatment adherence in adolescents with TB disease in Lima, Peru. I also have a grant from the Charles Hood Foundation to evaluate respiratory sequelae in adolescents from the Teens on TB Treatment cohort. Compared to the general population, adults with pulmonary TB have a higher risk of chronic fixed airflow obstruction, bronchiectasis, and poor respiratory-related quality of life, even despite successful TB treatment. No pediatric studies have examined post-TB lung sequelae. Knowing whether residual lung problems occur in children and adolescents is important for optimizing patient management.

Evaluation of Post-Tuberculosis Lung Function in Adolescents
Compared to the general population, adults with a history of tuberculosis are at risk of chronic fixed airflow obstruction and poor respiratory-related quality of life, even despite successful tuberculosis treatment. No pediatric studies have examined post-tuberculosis lung sequelae, yet knowing whether residual lung problems occur in children and adolescents is important for optimizing patient management and improving public health. The proposed project will evaluate respiratory sequelae in adolescents who are successfully treated for pulmonary tuberculosis.

Counting Kids: Enhancing Detection of Pediatric Tuberculosis in Ukraine
Through a review of autopsy and hospital records in Ukraine, this study will identify and quantify children with tuberculosis disease who were not diagnosed. A prospective arm will evaluate whether the addition of diagnostic tools to clinicians’ armamentarium can enhance detection of childhood tuberculosis disease.
Teens on TB Treatment: Can We Predict Adherence?
This International Research Scientist Development Award (IRSDA) will characterize adolescent-specific risk factors for poor adherence to TB treatment. The study will culminate in the derivation and validation of a clinically applicable prediction rule that identifies adolescents at risk for poor adherence to therapy for drug-susceptible pulmonary TB. At the same time, this IRSDA will serve as a vehicle for the PI to become an independent physician-scientist in global health research.
