Research Interest

The overarching goal of our group is to understanding how microbes have adapted to the gut environment and the implications for host health. The taxonomic scope of our work ranges from assessing total microbial community diversity to targeted investigations of particular species. We are particularly focused on Methanobrevibacter smithii, the most prominent archaeon in the human gut. Multiple studies have shown that M. smithii is heritable in humans, suggesting a role for host genetics in the ecology and evolution of the microbe. At a broader taxonomic scale, our group is assessing how vertebrate evolutionary history and ecology explains gut microbial community variation. In the pursuit of our biological goals, we have developed a number of bioinformatic approaches to more efficiently gain insight from next generation sequencing data.
