Research Interests
My overall research objective is to understand how resource availability influences plant physiological function and how these changes at the whole-plant level drive ecological processes. Such research is critical to understanding how species and communities will respond to modifications in environmental factors due to global climate change, N deposition, and anthropogenic disturbance. My previous research has focused on how nutrient deficiencies in desert shrubs influence organismal-level processes such as seed production, survival, and growth and how these processes impact population dynamics. This work has expanded into more detailed studies into the physiological and ecological controls on nutrient conservation in a suite of desert and chaparral shrubs. Additionally, I have begun work on the physiological and morphological traits that influence the competitive ability of invasive species. My research at the plant-soil interface is highly relevant given current pressures on native environments. By understanding plant physiological responses to these changes, we can better predict feedbacks on community dynamics and ecosystem processes.
