Alpine ecology, climate change, conservation, microrefugia, wildlife habitat, spatial ecology, remote sensing.
I am most interested in how terrain and climate interact to influence habitat use and occupancy at different scales and across environmental gradients. Most of my work centers on the American pika, a microclimate-limited mammal of western North America that may be threatened by climate change. I have used radio telemetry and passive integrated transponder (PIT) tags to track pikas habitat use through the year. I also use remote sensing data and occupancy surveys to model the effects of terrain in forming suitable microhabitat as shelter from the extreme alpine environment.
