Research Interests

I am a forest ecologist whose research (both greenhouse and field based) focuses on plant-soil feedbacks as a mechanism for shaping community composition, structure and productivity of temperate and tropical forests.  In particular, I am interested in feedbacks between plants and their soil community (both damping-off and mycorrhizal fungi as well as abiotic mediated feedbacks) and the impact that these feedbacks can have on maintenance of tree species diversity, exotic plant invasions as well as native species shifting range boundaries due to climate change.  I also investigate how abiotic factors (e.g. climate, light, soil fertility or moisture) can impact the occurrence or strength of these feedbacks. I use a mechanistic approach in my research to investigate the causes or processes underlying patterns occurring at the community level.
