Research
As a biogeochemist and ecosystem ecologist, my research in the Aquatic Biogeochemistry Lab focuses on better understanding the biogeochemical cycles within various ecosystems spanning from coastal wetlands to agricultural soils, and how these elemental cycles may be influenced by changes in the environment. Current research is investigating properties that regulate soil organic matter decomposition of wetland and agricultural soils as well as studying how changes in hydrology and water chemistry within the Indian River Lagoon impact greenhouse gas fluxes and ecosystem function of coastal wetlands.
