Research Areas:
1. Genome evolution in pathogenic bacteria. Comparative genomics, phylogenetics, and molecular biology are used to identify important events in the genome of pathogenic bacteria and understand the effects of genes and pathways marked by these events.
2. Evolution and development of gut microflora. 16S rRNA fingerprinting and sequencing is being used to examine development of the highly complex gut microflora in mammalian model systems, with the ultimate goal of identifying host genes that affect gut flora development.
