Our group studies microbial population diversity, ecology, and evolution. We focus primarily on freshwater and marine systems, and we use a combination of laboratory experiments, field observations, and computational analyses. Our current projects include 1) the role of marine viruses in biogeochemical processes; 2) the physiology and genetics of photoheterotrophy; and 3) phylogenetic and metabolic diversity of microbes in the Laurentian Great Lakes.
