Welcome to the Newton Lab at UW-Milwaukee
The organisms that we cannot see, the microorganisms, dominate biodiversity on Earth. Despite the sheer magnitude of these organisms, we know comparatively little about the diversity of microbes in most environments, how those microbes interact with their environment and each other, or how human activities alter microbial assemblages.
In the Newton lab, we study the microbial ecology of aquatic ecosystems. In particular, we focus on how human activities influence the structure and activity of microbial communities. We use a combination of field, laboratory, and computational approaches to explore the distribution and properties of microorganisms across a range of aquatic systems, including: inland lakes, wastewaters, groundwater, and aquaculture systems. In each of these systems, we investigate both microbial communities and the individuals or populations that make up those communities. Much of our work relies upon molecular and genomic techniques to gain access to the diversity of organisms present.
