Evolutionary and functional genetics of host x microbe interactions
When a microbe occupies the niche of an animal or plant, a conflict or compromise ensues that is dependent upon the efficacy of the host response and bacterial colonization capacity. We are interested in the biomolecular networks and genetic interactions between hosts and microbes that govern these interactions. Our long term goal is to combine knowledge from human microbiomes and model systems to address the interplay between host genetics and bacteria.
We seek to answer the following three questions: (1) Does human ethnicity and genetic variaiton persistently impact the microbiome? (2) What genes in animal models affect colonization, replication and transmission of maternally transmitted bacteria? (3) What host molecular mechanisms are deployed to trasmit bacteria from mom to offspring? and (4) What are the roles of dominance and epistasis among these genes and phenotypes?
