The goal of my research is to understand how the complex community of microorganisms that inhabit the intestines, known as the gut microbiome, influence vertebrate health and evolution. The primary aims of my research are: to determine (1) which microbiome functions consistently stratify healthy and diseased humans, (2) which microbiome functions are conserved across mammals, and (3) whether evolutionarily conserved microbiome functions are critical to health. Overall, this research will provide insight into the importance of specific microbiome functions to maintaining host health and will highlight their potential contribution to the evolutionary fitness of vertebrates.
