Current Research

High elevation ecosystem responses to acidic deposition in the southern Appalachian region; Loss of hemlock via hemlock woolly adelgid infestation and impacts on nutrient cycling; the potential of short rotation woody crop establishment on improving water quality in marginal farmlands of the Mississippi River Valley; impacts of land use changes in the southern Appalachians on ecosystem biogeochemical cycling; impacts of time, climate change, disturbance, and atmospheric deposition on stream chemistry in USFS EFRs across the U.S.

Research Interests

Forest soils, biological and environmental regulation of soil nitrogen transformations and biogeochemical cycles, nutrient transport within watersheds, long-term changes in soil carbon, nitrogen and available nutrients, effects of forest management practices and disturbance on soil carbon and nutrient transformations and availability.

Past Research

Examining the effects of elevation and vegetation gradients on forest nitrogen cycling; effects of prescribed burning on nutrient availability in xeric and mesic forests; structure and function of riparian soils and their role in regulating the movement of nutrients from hillslopes to streams; effects of forest management practices on soil carbon and nutrient cycling.

Why This Research is Important

Soil plays an important role in maintaining the ecosystem services provided by forests especially the headwater catchments present on National Forest lands, such as clean air and clean water.  As a vital component of all ecosystems soils contain large pools of carbon and nutrients in forests.  Disturbance of forests, by natural or anthropogenic impacts alters the cycling of both C and nutrients.  Understanding the regulation of biogeochemical cycling by and within forest soils is essential to decision making  by land managers.
