Dr. Kelly's career goal is to develop strategies that use targeted manipulation of the microbiome for the prevention and treatment of infections in high-risk groups of children. His current research focuses on elucidating the complex relationships that exist between sociodemographic factors, the upper respiratory microbiome and colonization by potential pneumonia pathogens among infants in Botswana. Ultimately, he aims to develop microbiome therapeutics that effectively prevent pneumonia and other respiratory infections in children.
