Research Interests

I am interested in the causes and consequences of landscape change, including natural disturbances, effects of anthropogenic land use, ungulate-landscape interactions, and invasive species. My research often considers past landscape change as a guide to understanding present and future condition, and integrates field studies, GIS, remote sensing and simulation modeling. Ongoing research projects within my lab group address disturbance ecology, woodland expansion, post-fire succession, and ecological restoration in Great Basin pinyon-juniper woodlands; fire history and ecology of mountain big sagebrush communities; fire ecology of the Sierra Nevada (Lake Tahoe Basin); and the ecology of tamarisk invasions along the Colorado River in Grand Canyon.
