My research interests are to understand how microbes change over time. Recent advances in DNA sequencing technologies brought us an avalanche of data: thousands of genomes and terabases of environmental DNA (metagenomes). I mine these data sets to assess the impact of horizontal gene transfer on microbial populations, find new ways to characterize microbial communities, and track down genomic signatures of microbial adaptations.
