She earned her M.D. from Johns Hopkins, where she also completed a residency in internal medicine and a fellowship in pulmonary and critical care medicine. Her research interests include idiopathic pulmonary fibrosis, interstitial lung disease and occupational lung disease. Dr. Horton is a graduate of the Leadership Program for Women Faculty and is also appointed on the Research Compensation Subcommittee at the Johns Hopkins University School of Medicine.

Dr. Horton has extensive research in pulmonary fibrosis, both in preclinical models and in human trials. Her lab has been able to help rapidly develop novel, genetic, tissue-specific models of immune dysfunction that were important in defining the immune regulation of fibrosis as well as to develop and test strategies to arrest and treat these diseases. She has utilized immunotherapy, in the form of T cell skewing, to prevent and reverse chemical-induced lung fibrosis. She is co-director of the Johns Hopkins Interstitial Lung Disease Clinic and served as primary investigator on clinical trials for idiopathic pulmonary fibrosis (IPF), which led to the discovery of one of the first treatments shown to improve quality of life in IPF. She is also site investigator for several past and present pharmacologic trials for IPF, including the hallmark ASCEND trial leading to the recent FDA approval of the first drug, pirfenidone, to slow down the progression of IPF.
