The Phillips laboratory studies metagenomic and genomic evolution underlying mammalian adaptations. Owing to the diversity and uniqueness of bats, most of our current projects utilize chiropteran systems.

Our work in metagenomics is geared to understand the relationship between the function and phylogenetic distribution of genes occurring in microbial genomes, the observed microbiome community structure of (and variance among) individual hosts, and host lineage-specific functional differences of metagenomes. By incorporating concepts developed in thefields of evolutionary biology, genomics, phylogenetics, physiology and ecology, this work builds systems-level understanding of organismal function.

Our work in genomics devolves from our interest in understanding how evolution of gene expression explains functional differences across lineages. For example, we are interested in identifying which genes have been recruited (i.e. turned on)in specific tissues of some bat species, but not others, and how these recruitments are adaptive to the different diets of these species. Related, we are developing projects to understand gene expression changes as a physiological response to flight and foraging. A uniting theme of our work is the goal of understanding the diversity of ways in which genomic function evolves to support success in different dietary niches.
