Research Summary

Checkley’s research has focused on characterizing the prevalence of, and risk factors and biomarkers for COPD in resource-limited settings in low- and middle-income countries. Specifically, he is leading observational studies on the association between household air pollution and lung function, as well as intervention trials of improved cookstoves to reduce household air pollution and improve cardiovascular and pulmonary outcomes. Dr. Checkley is involved in NIH-sponsored networks of Non-Communicable Chronic Diseases including the National Heart, Lung and Blood Institute sponsored Global Health Initiative and in the Global Alliance for Chronic Diseases, and is Principal Investigator in two household air pollution intervention trials using liquefied propane gas stoves and fuel distribution as an approach to mitigate pollution exposure. He also has research interests in critical care medicine, and has ongoing research projects on the use of mechanical ventilation and clinical outcomes in the United States and abroad.  Specifically, his research interests in critical care have focused on observational studies as a basis to establish best practices and/or interventions.  Dr. Checkley has lead observational studies in Peru and the United States to examine the role of patient and ICU organizational factors that may help identify interventions or changes in practice to improve patient-centered outcomes. Dr. Checkley has authored 200 publications in peer-reviewed journals (3884 overall citations with an h-index of 31) and is a member of the editorial board of six medical journals and serves as a frequent peer reviewer in multiple high-impact journals.
