My research focuses on understanding the factors influencing plant community structure and associated ecosystem functions. My previous work has focused on understanding how variation in plant competition, mycorrhizas, and plant-pollinator interactions alter plant communities, especially as it relates to invasion by non-native plants. Ultimately, the goal of my research is to make these interactions and their consequences more predictable by understanding how they relate to variation in plant traits. Most of this research has been conducted in grassland plant communities, and I have a growing interest in how grazing regulates the aforementioned interactions and the consequences for range health. I also dabble in plant-soil interactions in forested systems, and I remain keen on maintaining active research in this field.
