I use genomic and other molecular tools to study the interactions between wildlife, commensal microbiota, and pathogens. I am particularly interested in understanding how anthropogenic changes in population structure, habitat, and climate are altering the relationships between hosts and microbes, and what the potential consequences are for fish and wildlife population health. Much of my past work has focused on how the gut microbiome associates with disease, environment, and stress in ungulates, marine mammals, and salmonids. My current work with the Epps Lab involves understanding how infection dynamics drive immunogenetic adaptation of desert bighorn sheep populations in the southwestern United States.
