Microbial communities are complex food webs between cells with different metabolisms. I study how these microbial metabolisms interact using metagenomics and synthetic ecology. Specifically, I focus on interactions that occur when perchlorate, a toxic rocket fuel, is degraded by microbes. These studies will expand our understanding of the evolution and ecology of the the natural chlorine cycle and may produce new biotechnology.
