I am a plant and community ecologist who uses experimental and analytical methods to examine the mechanisms of community assembly, species interactions, and diversity. My past research has focused on testing the link between assembly and environmental gradients, seedbank dynamics, plant-soil feedbacks, plant traits, and plant-plant interactions. Due to the dynamic nature of ecological systems, my long-term research goal is to improve our understanding of how different scales of variability impact population and community dynamics as well as broader diversity patterns and ecosystem functions.

After spending the past ten years in Canada conducting research and obtaining my B.Sc. (Dalhousie University) and Ph.D. (University of Alberta), I am excited for the new opportunities and questions that will arise from studying the much warmer study system of the Sonoran Desert and its extraordinary diversity. At Tumamoc Hill, I am utilizing rich datasets the lab has amassed over the past 100+ years to answer questions about plant population and community dynamics over time. The data from the Spalding-Shreve plots and Saguaro monitoring program provides a unique opportunity to examine the long-term impacts of climate variability on plant populations and communities.
