Research Interests

The diversity of life has long fascinated biologists. Although biologists know a great deal about the diversity of plants and animals, we know very little about microbial diversity, despite the fact that microorganisms comprise most of life’s diversity.
Research in the Bohannan group is focused on the causes and consequences of microbial biodiversity. Recent work includes studies of the spatial scaling of bacterial biodiversity, the response of bacterial and archaeal communities to environmental change, and the role of spatial structure in the generation and maintenance of bacterial and viral diversity.
Prof. Bohannan is especially interested in promoting the integration of microbial ecology into the general science of ecology.
