Biography
Dr. Walter received graduate degrees from University of New Hampshire and Oklahoma State University and served as a post-doctoral Researcher at the USDA-National Wildlife Research Center and Colorado Cooperative Fish and Wildlife Research Unit for nearly 5 years. He conducts research to explore spatial ecology of various species throughout the U.S. using spatial analysis at the landscape-level to further our understanding of wildlife presence/absence, nutrition, and disease. Much of his primary research interests have focused on using various modeling techniques to understand spatial ecology of disease in ungulates in various regions of North America. He also uses genetics and stable isotopes to understand movements, nutritional ecology, and effects of invasive species on native non-game species at the landscape level. He regularly teaches a graduate course in spatial ecology, movement analyses, home range estimation, and disease epidemiology. In addition to exploring genetics of species at the landscape or regional level, Dr. Walter focuses on methodologies in movements, home range, and resource selection of avian and mammalian species. New tracking and telemetry technologies with global positioning system (GPS) technology have become more readily available for a variety of avian and mammalian species of various sizes. This GPS technology allows for remote data capture from a steadily increasing number of taxa, species, and individual animals.
