Research Interests

Microbial biogeochemistry; high latitude wetlands; methane production; sulfur cycling; mercury transformations in the environment; trace gases

Researchers in my laboratory study the role of microorganisms in the cycling of elements in depositional environments such as sediments, soils and wetland peats. I am especially interested in a) the production and consumption of trace gases and b) the transformation of toxic materials as well as their effects on microbial life. We are currently focused on two projects. In the first we examine phenomena that control the formation of biogenic methane in anaerobic freshwater wetlands at high latitude. In the second we investigate factors affecting the methylation and demethylation of mercury in soils, freshwater and marine sediments, as well as wastes associated with mining activities.
