Research Interests

The Phillips laboratory studies metagenomic and genomic evolution and function.

Our work in the field of metagenomics focuses on understanding the determinants of community assembly of microbiomes, and how microbiomes relate to health in wildlife and in humans.  Current research projects include the study of assembly of bat microbiomes, as well as how people's genetics determine the composition of their chronic wound infections. The latter is being conducted in collaboration with the Southwest Regional Wound Care Center and involves the development of the Wolcott Wound Care Research Collection at The Museum of TTU.

We also are investigating how post-transcriptional regulation during craniofacial development by the RNA-binding protein, Musashi-2, may be important for normal development and morphological differences among species.

Other projects focus on biodiversity and conservation of Texas mammals.
