My research is centered on developing a mechanistic understanding of watershed ecosystem function by studying how abiotic and biotic factors (e.g., species, environmental variables, disturbances) regulate carbon, nutrient, and water cycling processes. My personal research spans the continuum from the organism, to stands, to landscapes and includes determination of the roles of species and natural and anthropogenic disturbances (including forest management activities) in regulating ecosystem hydrologic processes. I am conducting a combination of ecophysiological and ecosystem studies at multiple scales to understand and forecast how evapotranspiration and streamflow are regulated by biotic and abiotic factors.
My primary areas of emphasis are: (1) quantifying rates of and driving mechanisms influencing water and carbon fluxes in trees across a range of environmental conditions; and (2) scaling these measurements spatially and temporally, often in a predictive manner, to make inferences on forest ecosystem processes (e.g., forest hydrologic and carbon cycles) under changing management or climatic conditions.
Why This Research is Important
Being able to resolve the importance of species identity on the water cycle is challenging, but critical for addressing questions of management, natural disturbances, and climate change on stream flow. Management and natural distrubance often create forests with specific species and structure. Climate change will have a similar effect. Because the average rate at which ecosystems must shift geographically to keep pace with changing temperatures as a result of global warming is 0.42 km/year, most ecosystems will face temperature increases faster than species will be able to migrate or adapt, leading to mass extinction of many plant species. Thus, developing an understanding of species-level variation on forest processes will allow us to predict the impacts of invasive insects (e.g. hemlock woolly adelgid) and disease (e.g. chestnut blight), climate change (i.e., by linking stress physiology with population dynamics), and develop management options to adapt to or mitigate the impacts on stream flow.

- Assessment of the Interaction of Climate Change, Fire, and Forests in the U.S. Published (2014)
- Fire has been one of the most frequent and severe disturbances to ecosystems globally and, as such, one of the major regulators of forest composition, function and dynamics. Any consideration of forests under a changing climate regime, therefore, must be viewed through a prism of fire interactions. A special section of the September issue of Forest Ecology and Management assesses the interactions among fire, climate change, and forests for five major regions of the United States.

- Few studies have examined how insect outbreaks affect landscape-level hydrologic processes. In this study, Forest Service scientists report the hydrologic effects of the invasive, exotic Hemlock Woolly Adelgid in a headwater catchment in the southern Appalachian Mountains.
- Quantifying the Role of National Forest System Lands in Providing Surface Drinking Water Supply for the Southern United States (2014)
- In the South, as in the rest of the U.S., people and communities depend on forests as the headwaters for clean and dependable water supply. A new publication by U.S. Forest Service researchers provides details at the landscape level on the quantity of water southern communities receive from federal, state and private forest lands. The report provides, for the first time, scientifically credible information on the exact extent and importance of forests to drinking water in the South.
