Research Interests

I am fascinated with the challenges of working with diverse agencies and organizations to sustain natural resources and wildlife across large spatial extents.  For that reason, I am pleased to be part of the Landscape Conservation Initiative at NAU, which includes the Lab of Landscape Ecology and Conservation Biology.  In addition to large landscape research within the Lab, the Landscape Conservation Initiative also provides opportunities for collaborative planning across agencies, and offers novel education experiences that are outside of the traditional university format.  

My early research focused on three primary themes within the field of landscape ecology: the effects of forest fragmentation and habitat loss on the American marten; the influence of landscape pattern on northern goshawk home ranges; and the behavior of landscape metrics under different scenarios of landscape fragmentation. More recently, I have developed broad scale monitoring protocols for wildlife populations and habitat that have become agency standards for the Forest Service.  With a career background that straddles science and management across four federal agencies, I continue to work with land managers on current issues that encompass broad scales.
