Research Interests:

My research interests are in plant community ecology, plant-soil microbe interactions, and plant-animal interactions, utilizing a combination of experimental field and greenhouse studies. The majority of my research focuses on rangeland ecology and management, fire ecology, nutrient dynamics, and grassland restoration, with an emphasis on belowground mechanisms such as mycorrhizal symbiosis and belowground populations of meristems.  Dynamics within the soil community can be a major driver of the plant community. For example, our research indicates that mycorrhizal fungi contribute to community processes and functions through their establishment of linkages and feedbacks between plants and nutrient cycles. Other research I am currently involved with includes invasive species and woody plant expansion in grasslands, restoration of rangelands, and the importance of resource availability (specifically soil P, N, and light) as controllers of the mutualistic function of arbuscular mycorrhizal symbiosis.
