Doctor Amy Churchill

Amy Churchill joined HIE in 2017 as a research fellow in Ecosystem Function and Integration. Her research focuses on plant responses to extreme climate conditions within the PAstures in Climate Extremes experiment (PACE) applying drought and elevated temperatures. She is interested in examining both temporal (phenological) and structural (biomass and nutritional) plant responses to extreme climate conditions, and in particular to understanding the nature of plant species interactions as environmental conditions change.

She completed her doctoral work in 2017 at the University of Colorado Boulder, where her research emphasized community structure and controls on ecosystem processes associated with consequences from nitrogen deposition. Her research was conducted both along natural gradients and through experimental manipulations comparing responses of different plant communities in the alpine to elevated nitrogen deposition. During her time as a PhD candidate Amy was the primary instructor for an undergraduate upper division course on plant ecology, and co-instructed a graduate level science writing seminar.

Her Master’s thesis at the University of Alaska Fairbanks focused on the responses of plant community and ecosystem carbon cycling to changes in hydrology associated with climate change in the boreal forest.
