Daniel B. Horton, MD, MSCE


Daniel Horton is a pediatric rheumatologist and pharmacoepidemiologist who performs clinical, translational, and health services research. He started at Rutgers in 2016 as an Assistant Professor and Chancellor’s Scholar in the Department of Pediatrics at Rutgers Robert Wood Johnson Medical School and was a founding faculty member of PETS in 2017. He graduated from Harvard Medical School (MD, 2008) and completed pediatrics residency at the Children’s Hospital of Philadelphia (2011), followed by pediatric rheumatology fellowship at Nemours/A.I. duPont Hospital for Children (2014) and research training in clinical epidemiology and pharmacoepidemiology at the University of Pennsylvania (MSCE, 2015). 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. Most recently he has collaborated in 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. At Rutgers, Dr. Horton serves as the Chair of the PETS Faculty Search Committee, Co-Chair of the Pediatric Resident Scholarly Oversight Committee, Director of the Clinical Epidemiology Certificate Program at the School of Public Health, and Co-Leader of the Team Science Core of NJ ACTS (CTSA). He has held leadership positions within the International Society for Pharmacoepidemiology and the Childhood Arthritis and Rheumatology Research Alliance, is a consultannt to the FDA Drug Safety and Risk Management Advisory Committee, and is Associate Editor for the journal, Pharmacoepidemiology and Drug Safety.
