Research Program:
I am a paleoecologist and biogeographer, bringing the perspectives of space and time to bear on questions in ecology and global change science. My work takes a community ecology approach to help understand how species and their interactions have responded to interacting drivers (like climate change and extinction) through time. I’m especially interested 1) novel communities and ecosystems 2) the legacies “biotic upheavals” like the extinction of Pleistocene megafauna, 3) biotic drivers of landscape change on long (>1,000 years) timescales (e.g., herbivory, dispersal, insect outbreaks), and 5) what the paleorecord tells us about the ability of plants to migrate in response to climate change.
