Dr. Tamara Harms is a research associate at the University of Alaska-Fairbanks. Trained as an ecosystem ecologist and biogeochemist, Tamara conducts studies of nutrient cycling in watersheds, often focused at land-water interfaces. Her research in the arctic and sub-arctic has focused on the consequences of climate change for cycling of nitrogen, an essential nutrient to all living things. To study nutrient cycles, Tamara analyzes the nutrients present in soils and water, conducts experiments to measure rates of microbial processes that transform nutrients, and identifies how nutrients are transported from land to water. In particular, she is interested in potential consequences of thawing permafrost for nutrient cycles.
