Position title: Spatial Applications, Biologist
1998 M.S., Resource Analysis, Saint Mary’s University of Minnesota
1995 B.S., Ecology, Winona State University
I have interdisciplinary expertise in biology, geographical information systems (GIS) and application programming. My work emphasizes landscape ecology and the creation of flexible tools and models to assess species habitat.
