Modeling Carbon Dynamics in Constructed Wetlands

To learn more about my research on carbon cycling in constructed wetlands click here….

I am currently a PhD candidate in the Soils and Biogeochemistry graduate group at the University of California, Davis.










Research Interests

My general research interests revolve around understanding the biogeochemical cycling of nutrients across different spatial and temporal scales. In particular I am interested in these patterns and processes as they occur in different ecotones. Much of my research has involved carbon and phosphorus cycling in seasonally saturated constructed wetlands. I am interested in how long-term nutrient loading from agricultural runoff effects the biogeochemical cycling of nutrients in wetland systems. In many of my research projects I integrate both field and laboratory based analysis with geostatistical and spatial modeling in the attempt to understand biogeochemical processes across different spatial and temporal scales. My current research projects include: (i) phosphorus-iron-sulfur cycles at the sediment-water column interface, (ii) the temporal and spatial variability of net ecosystem production in a constructed wetland, and (iii) the retention and transformation of reducible phosphorus in a constructed wetland. Other research interests include water quality, remote sensing, and GIS.


Research projects that I am currently conducting include:

  1. Carbon dynamics in seasonally submerged wetland soils
  2. Iron-Sulfur-Phosphorus cycling in constructed wetland sediments
  3. Temporal and Spatial Variablility of Aquatic Metabolism in a Constructed Wetland
  4. The cycling of reducible phosphorus in a constructed wetland and its role in eutrophication
  5. The fate of phosphorus in verticle seepage from constructed wetlands
