People in the Lab
Hall Cushman
Hall has diverse interests in many areas of basic and applied ecology. Early in his career, his research focused on the dynamics of insect mutualisms. He then moved on to study the community-level consequences of plant invasions and the impacts of mammalian herbivores on plant communities. In the past decade, Hall has shifted his research focus to climate-change ecology and addresses the dynamics of montane ecosystems, with particular emphasis on patterns in and drivers of forest decline and tree regeneration.

Mia Goldman
Mia is interested in the factors that drive the occupancy and persistence of the imperiled American pika across its range in the Great Basin. She hopes to analyze a wide range of factors operating at different spatial scales including climate change, topography, the ratio of exotic to native plant species, and grazing history and intensity.
