Biography

I received B.S. and M.S. degrees in Wildlife Resources and a M.S. degree in Statistics from the University of Idaho, as well as a Ph.D. in Fisheries and Wildlife from Michigan State University. My postdoctoral research is focused on modeling the distribution and abundance of wetland birds.

Research Interest

Wildlife ecology and management, applied population ecology, structured decision making, statistical ecology My research interests are focused on the intersection of ecology, natural resource management, and applied statistics, including population and statistical ecology, landscape-scale conservation of wildlife, and decision-theoretic applications in conservation and resource management. This work spans a variety of species and study systems (both terrestrial and aquatic), where a unifying theme is application of advanced statistical and ecological modeling tools to address real-world challenges in the conservation and management of animal populations.
