Faculty Profile


Research interests in the Ramer-Tait laboratory are focused on understanding host-microbiota interactions. In particular, our research program aims to: (1) determine the causative relationships between the gut microbiota and chronic, inflammatory diseases, (2) understand how dietary interventions, including dietary fibers, can be used to improve inflammatory diseases via modulation of the gut microbiota, and (3) develop new approaches to disease prevention and treatment that include microbiome manipulation.
