  • BS SUNY - College of Environmental Science and Forestry 1995

Biography

After finishing my Ph.D. I served as a post-doctoral Researcher at the National Wildlife Research Center for nearly 5 years. A majority of my research explores spatial ecology of various species throughout the U.S. using GIS to further our understanding of wildlife presence/absence, nutrition, and disease.

Teaching Interest

I teach graduate courses in spatial ecology, movement analyses, home range estimation, and disease epidemiology.

Research Interest

My primary research interests have focused on using various modeling techniques to understand spatial ecology of disease in ungulates in various regions of North America. I also use stable isotopes to understand movements, nutritional ecology, and effects of invasive species on native non-game species at the landscape level.
