Broadly, I investigate processes shaping ecosystem function, and how ecological processes respond to global environmental change. My current projects with BiRN center around the global challenge of feeding a growing world population while minimizing negative environmental externalities. Agricultural technologies have raised global crop yields over the past several centuries, yet increasing environmental variability associated with climate change can have large consequences for crop productivity. In collaboration with ALUS Canada, my current projects ask how farming management practices can influence productivity in variable climates.
