  The UML Biogeochemistry Laboratory investigates the role of organisms in controlling elemental cycles in nature. In particular, we focus on anaerobic processes in both freshwater and marine environments and the role of microorganisms in the cycling of S and C, and in metals, especially mercury. General themes of the laboratory are methylation of elements by bacteria including sulfur and metals and production and consumption of gases. The group conducts studies in several locations worldwide, such as the northeast USA (New England and New York), Alaska, Texas, Idaho, and internationally in Slovenia, Italy, Spain and Switzerland. Habitats investigated include freshwater and marine sediments and wetlands and uplands.
