​Bio

I am a terrestrial ecosystem ecologist, specializing in plant-insect interactions and the ecology of non-native invasive plants. Broadly, I am interested in understanding how soil resources, plant competition, herbivory, and other biotic and abiotic factors influence the abundance and distribution of plant species and plant communities across the landscape.

 

The majority of my research to date has occurred in short- and mixed grass prairie and ponderosa pine woodlands of the Colorado plains and Rocky Mountain Front Range. One of my primary research thrusts is to investigate how changes in climate influence plant communities and land management activities, particularly for control of non-native invasive plant species. As a primary focus, I am interested in enhancing the field of restoration ecology – specifically, re-establishing and conserving diverse plant communities, through a research approach that identifies the important bottom-up (resources) and top-down (biotic) controls on plant communities.
