Research
My research focuses on analysis of the microbial communities associated with healthy and diseased acroporid corals. Specifically I am attempting to determine which bacteria are normally present on healthy corals and determine how the community structure is altered in diseased corals. While I use both culture-based and genomic approaches to address these issues, the bulk of my analyses have utilized large-scale 16S rRNA.gene library analysis.
