Research in the Mosier lab centers around (1) microbial biogeochemistry—understanding microbial function in the environment, and (2) microbial ecology—understanding and predicting the driving factors that shape microbial community structure and function in the environment. Earth's biosphere and climate are regulated by biogeochemical carbon and nitrogen exchanges between the land, oceans and atmosphere that are chiefly driven by microorganisms, and yet much remains to be learned about these critical processes. The Mosier lab examines the biogeochemistry and ecology of carbon and nitrogen cycling microbes in aquatic environments and their responses to environmental change. These themes are addressed by exploring the connections between genes, organisms, communities and the environment through the application of field and laboratory studies.
