Current Research

(1) Examine the impacts of wildfire and postfire rehabilitation activities on forest overstory and understory composition and structure; (2) Clarify how, when, and why overstory and understory plant communities change as a result of ongoing insect and disease epidemics; (3) Investigate the impacts of forest management activities (e.g., slash pile burning, salvage logging) on native and exotic plants

Research Interests

My research activities address the impacts of natural and human disturbances on plant populations and communities in Rocky Mountain forests.
