I work at the interface of ecosystem, landscape and population biology. My goal is to apply cutting-edge “usable” science to the challenges of restoration, species invasion, and environmental change. My lab works with a variety of conservation groups, government agencies and land managers.
Work in my lab focuses on multiple areas of plant ecology, primarily on the interactions between plants and their resources, ranging from plant adaptations to low resource availability, to how plants influence soils and subsequently ecosystem function and biodiversity.
My research focuses on two pervasive and inter-related forms of biological change: disease emergence and species invasions. Our group uses long-term data, ecological experiments and modeling approaches to examine the factors that drive disease emergence and biological invasions.
My research and teaching interests are focused on the processes controlling hydrologic fluxes in mountainous regions and within the greater Earth system. My projects utilize ground-based observations, remote sensing, and computational modeling to obtain comprehensive understanding of hydrological processes.
My research is in biogeochemistry, with studies ranging from the carbon cycle to atmospheric mineral aerosols. I am interested in how human activities influence Earth systems and the impacts of changing biogeochemical cycles on natural systems and human society.
