Broadly, Dr. Horton’s research focuses on the uses, safety, and effectiveness of medications in children, with particular interests in antibiotics, anti-inflammatories, and anti-rheumatic drugs. He performs research on the origins and treatment of juvenile idiopathic arthritis, including the role of antibiotics, the microbiome, and the management of disease remission. He has conducted clinical, translational, and interventional research on COVID-19 in pediatric and adult populations. His work has been published in Pediatrics, JAMA Pediatrics, Arthritis and Rheumatology, Annals of Rheumatic Diseases, American Journal of Epidemiology, Circulation, Proceedings of the National Academy of Sciences, and elsewhere. Dr. Horton’s research has been supported by grants from the National Institutes of Health (NIAMS, NIAID, NCATS, NICHD) as well as various research foundations.
