Research

Dr. Leonard’s research is focused on predicting and preventing celiac disease through precision medicine. Precision medicine is an emerging approach to disease prevention and treatment that takes into account individual variability in genes, environment, and lifestyle.

Her current work includes identifying biomarkers that can predict intestinal healing in patients with celiac disease, building translational models capable of predicting autoimmune disease in high-risk individuals and working with Dr. Alessio Fasano on the NIH-funded Celiac Disease: Genomic Environment Microbiome and Metabolomic Study (CDGEMM).
