THE MICROBIAL ECOLOGY LAB studies the biogeochemical interactions between microbes and trace elements in nature.

Our research ranges from the cellular to the ecosystem level, and includes estuarine, marine, lacustrine, terrestrial and wetland ecosystems. Our work encompasses microbial ecology, biogeochemistry, trace metal chemistry, and analytical chemistry.

Much of our work concerns the biogeochemical cycle of mercury, particularly the production of methylmercury by natural bacteria. These studies provide information on the effective control of mercury pollution in the environment.
