Research in the Barrett Laboratory

Research in the Barrett Lab addresses the influences of soils, climate variability, hydrology and biodiversity on biogeochemical cycling from the scale of microorganisms to regional landscapes. Presently, most of my research is conducted in Polar desert ecosystems of Antarctica where I am focusing on how subtle changes in climate affect carbon cycling through altered processes meditated by soil organisms. In other ongoing projects I am studying the roles of physicochemical gradients and microorganisms in facilitating transformation and transport of nitrogen-compounds across terrestrial-aquatic interfaces.

• Biogeochemical cycling in hydrological margins.
• Environmental controls over soil biodiversity and ecosystem functioning.
• Carbon cycling in the McMurdo Dry Valleys
