Amanda Ramer-Tait portrait


Dr. Ramer-Tait has built an internationally recognized research program that focuses on how the microbes living in the human digestive tract (known as the gut microbiota) influence human health and disease. Her work also aims to develop novel dietary interventions that alter the gut microbiota to treat chronic diseases, including obesity, metabolic syndrome, and inflammatory bowel diseases. Dr. Ramer-Tait has authored over 90 peer-reviewed publications and received research funding from the Crohn’s and Colitis Foundation, the National Institutes of Health, and the US Department of Agriculture. She also co-directs the Complex Biosystems PhD program at UNL and teaches courses on immunology, microbiology, and functional foods.
