Kathy has over 15 years of experience as a spatial ecologist. Her research integrates the fields of landscape ecology, wildlife biology, landscape genetics, and biostatistics to conduct quantitative analyses on wildlife populations and ecosystems. It was during Kathy’s first field job in the vast wildlands of Alaska, when she became inspired to work to maintain wild places and the unique resources and benefits they confer. Since this time, Kathy’s research has focused on understanding and quantifying how patterns and processes of human-driven disturbance and climate change affect wildlife populations and large ecological networks. Kathy is particularly interested in modeling connectivity within and among protected lands and in providing spatial products and decision-support tools that are useful to managers and stakeholders.
