Research Interests

Our research focuses on biogeochemical cycling of carbon, nitrogen and phosphorus in aquatic systems including coastal and freshwater wetlands, estuaries and lake sediments, treatment performance of constructed wetlands for nutrients and pharmaceuticals removal, dynamics of internal nutrient loading, microbial-mediated nutrient transformations, plant-nutrient-soil dynamics.  We provide critical research in helping coastal restoration managers to make informed decisions.
