RESEARCH FOCUS
Biogeochemical cycling of organic carbon and other nutrients in wetland soils and aquatic ecosystems; role of organic matter as driver and modulator of wetland ecosystem functions; role of aquatic vegetation in DOM/POM/nutrient dynamics, soil accretion; fire ecology of wetlands and impacts to biogeochemical cycles and ecosystem responses, soil subsidence; coastal processes with respect to seagrass and mangrove productivity and organic matter cycling, sub-aqueous soil pedogenisis; soil biogeochemical processes associated with coastal forest retreat and development of salt marsh ecosystems; wetland soils as natural water quality treatment systems. Current projects (pdf).
