Dr. Hall studies the consequences of human activity on the cycling of nutrients within and between terrestrial ecosystems. She uses an experimental approach to pursue questions across ecosystem types (tropical, temperate, arid, urban) and at multiple scales (microbial to regional and global). Her current research investigates 1) the effects of anthropogenic nutrient deposition of carbon and nitrogen on ecosystem processes, and 2) the effects of land use on land cover on ecosystem functioning. Dr. Hall teaches courses on biology and society, soil ecology, and the socio-ecology of residential landscapes.
