RESEARCH OVERVIEW:

My research interests:

I am a plant ecologist broadly interested in how abiotic and biotic conditions, evolutionary history, and disturbance shape plant species distributions and plant community composition across a variety of spatial scales. My current research has two focuses, but both examine the important question of how plant species will respond to global change. I accomplish this by focusing on population dynamics and drivers of plant diversity along environmental gradients in mountains, and in response to disturbance in the sagebrush steppe of western North America. I use observational, experimental, and empirical modeling approaches to understand the mechanisms that assembly plant communities and cause observed biogeographic patterns.
