Expertise: Plant physiology and ecology, with an emphasis on plant-soil interactions
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. Currently, my research program at John Carroll University has two main foci. First, my lab investigates questions regarding plant nutrient resorption and storage and how these physiological functions influence both individual as well as community and ecosystem processes (both nutrient limitation and soil nutrient cycling). Working with chaparral, desert, and rangeland species, we seek to understand the physiological and ecological controls on plant nutrient conservation. Secondly, I am interested in 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.
