Research Interests

Microbial Genomics and Metagenomics

The total number of prokaryotic cells inhabiting our planet is estimated to be in the nonillions (1030). Those within and on the human body number mere trillions (1014), yet their identity, distribution and function are still obscure. Significantly, the contribution and effect of the human “microbiome” on human health and disease is still largely unknown.

Progress has been made to catalog and characterize these organisms and their genomes, but most studies have focused on a single body site, a single disease (often on a single pathogenic organism), and most of these have been restricted to culture-dependent methods. Recent advances in DNA sequencing technologies have enabled more comprehensive analyses of the human microbiota; thus, a concerted effort was launched to leverage these advances to expand our insight into the microbial communities that inhabit distinct niches within the human body. It is now possible to sequence the DNA of the collective genome (or metagenome) of entire communities of microbes from all body sites, effectively enabling the characterization of the “Human Microbiome”.

Since 2007, our laboratory has played a leadership role in the NIH Human Microbiome Project (HMP) (commonfund.nih.gov/hmp/). The overarching goal of the HMP is to develop tools and resources for characterization of the human microbiota and to relate these microbiota to human health and disease. A primary focus of the laboratory has been the sequencing and annotation of hundreds of bacterial “reference genomes” to contribute to a catalog of strains (www.hmpdacc.org) that serves as a database against which metagenomic data from human samples are compared. We also played an active role in the processing and characterization of thousands of samples collected from a healthy cohort of subjects and we developed “mock” metagenomic communities to aid in benchmarking activities for HMP sample preparation and sequencing (www.beiresources.org).
Current and ongoing activities are focused on comparative microbial genomics, 16S ribosomal RNA gene surveys and metagenomics of clinical and environmental samples.
