My research focus is fairly broad but follows the focus of either methane and carbon dioxide production, emission and cycling, and/or stable isotope analysis. At this time I am working in six different areas:
- Wetlands, looking at permafrost decomposition in the northern boreal zone;
- Food webs, learning about trophic relationships in estuaries;
- Reducing methane emissions to the atmosphere, designing landfill cover soils which promote the growth of methane-consuming bacteria;
- Methane gas hydrates, which some estimate may be a large reservoir of fossil fuel to be mined;
- Pine forests, which can be large sinks for excess CO2; and
- Groundwater discharge, an overlooked process which is important to the nutrient budgets of coastal waters.
I am also involved in the new Biogeochemical Dynamics Program at FSU. The Biogeochemical Dynamics Program is an interdisciplinary research-oriented, graduate-only program within the FSU College of Arts and Sciences which focuses on environmental biogeochemistry.
