Our microbial metagenomics research focuses on evaluating genetic basis of important host-associated microbiome phenotypes (e.g., anti-pathogen metabolite and tetrodotoxin production).

We are interested in evaluating co-evolutionary associations between hosts and pathogens through changes in immunogenetics. In addition, part of our research explores the influence of host immunogenetics (i.e., MHC genes) on skin microbial community composition.

A lot of research has explored the inhibition of chytrid growth by amphibian skin pathogens; however, there is a lack of knowledge regarding pathogen effects on skin symbionts. We explore possible co-evolutionary interactions between fungal pathogens and host-associated microbiomes.

Western pond turtles are the only native Californian pond turtle species. These turtles are considered threatened in the state. Factors such as urbanization, invasive species and infectious diseases threaten western pond turtles throughout their range. Our lab is exploring the interactions between these risk factors and the microbiomes of western pond turtles.
