Wetland Biogeochemistry Laboratory

Graduate Research Professor, Biogeochemistry
Conducts basic and applied research on biogeochemical cycling of nutrients/contaminants. Develops biogeochemical indicators to evaluate changes in ecosystem functions in wetlands and aquatic systems.

Todd Z. Osborne
Research Assistant Professor

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.

Assistant Professor
Wetland nutrient assimilation and storage processes, vegetative succession dynamics, wetland macrophyte ecophysiology, and ecological engineering design using wetland processes to improve water quality and enhance ecological function of altered landscapes.

PATRICK INGLETT
Assistant Professor, Biogeochemistry
Research and teaching related to biogeochemical processes in subtropical ecosystems. Emphasis on coupling of C, N and P cycles. Traditional physicochemical analysis combined with novel enzyme and microscopy, and enrichment and natural abundance level isotopic methods.

Associate Professor
Emphasis on minimizing human impacts on natural hydrologic ecosystems, including watersheds, wetlands, and aquifers. Develops techniques for characterization and remediation of contaminated soil and groundwater.

Courtesy Assistant Professor
Conducts research to examine the effects of nutrients and hydrology on the ecology of Everglades marshes and tree islands. Sue’s current research includes the cattail habitat improvement project (CHIP), a large-scale field experiment designed to examine how creating openings in the dense vegetation of enriched and moderately areas of the Everglades will result in increased ecological structure and function. Specifically, this multi-disciplinary project will examine how food web dynamics change in response to changing vegetative structure and evaluate to what extent the ecological functions of these created open areas compare to the natural Everglades

Professor
Studies the adaptation of microbial communities to human impacts, including shifts in microbial community structure in upland and wetland soils. Research interests also include the molecular evolution xenobiotic-degrading genes and mobile DNA elements in soil bacteria.

Research emphasis on nutrient cycling (phosphorus and nitrogen) processes operating within large treatment wetlands that were constructed in South Florida to aid in the restoration of the Everglades.
