Postdoctoral Research Projects
All animals host microbial communities (microbiotas). In some animals, including humans, the diversity of microbial genes is far greater than the diversity of host genes, raising the intriguing possibility that microbial genomes could be a source of genetic variation contributing to host adaptation. My postdoctoral research investigates the role of gut microbes in facilitating adaptation in their hosts. Specifically, I assess how host evolution, microbe evolution, and microbial diversity interact to determine adaptation to environmental stressors, such as toxins and high temperature. I use the worm Caenorhabditis elegans and its community of gut bacteria as an experimental model.
