Research Interests
I utilize a combination of field-based ecological research and landscape-level ecosystem simulation modeling approaches to examine the impacts of climatic change on terrestrial ecosystems. My recent work examines the impacts of climatic variability, fire, and forest management on the long-term landscape-level carbon balance of longleaf, loblolly, and pond pine forests in Atlantic coastal plain. My work on these ecosystems also examines the relationship between soil properties, vegetation, and avifaunal communities, and the ways in which these relationships are impacted by ongoing efforts to restore the longleaf pine ecosystem through a reintroduction of fire to the landscape.  I have also been examining the impact of intra- and inter-annual climate variability on seasonally drought-stressed ecosystems, particularly those that may be vulnerable to ongoing climate change. Most of my work in this regard has focused on the Tenderfoot Creek Experimental Forest, an experimental forest watershed in central Montana. I am currently working toward expanding my research to other ecosystems as well.
