Genomic Analysis of Phage
Phage, viruses that infect bacteria, are the most abundant biological entities on the planet. By killing bacteria, phage have an enormous influence on global biogeochemical cycles and help maintain microbial diversity.

Diversity of Coral-Associated Bacteria
To determine which bacteria are normally associated with reef-building corals, we have been analyzing bacterial diversity in coral samples by high-throughput sequencing of bacterial 16S rDNAs.
