Her lab uses analytical chemistry, physiology, ecology, and remote sensing to predict mechanisms and consequences of the chemical interactions between plants and vertebrate herbivores from cells, to individual organisms, to landscapes. She has applied these approaches to understand sage-grouse interacting with sagebrush in Western USA and ptarmigan and their interactions with birch and willow in Scandinavia. Her projects seek to explain seasonal, biogeographical, and co-evolutionary patterns of plants and vertebrate herbivores and help contribute to the management of these species.
