Phone: 608.781.6228
Fax: 608.783.6066

Education:
1998 M.S., Resource Analysis, Saint Mary’s University of Minnesota
1995 B.S., Ecology, Winona State University

Primary Responsibilities/Activities:
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. 

Research Interests:

• Evaluating species response to landscape changes
• Regional habitat modeling
• Spatial decision support system development
• Database development and analysis

Active Projects:

• LiDAR and Bathymetry data integration
• Providing GIS support to the Fishers and Farmers Partnership of the National Fish Habitat Action Plan
• Anticipated Effects of Development on Habitat Fragmentation and Movement of Mammals Into and Out of the Schoodic District, Acadia National Park, Maine
• A Tool for Prioritizing Management Units at Morris Wetland Management District
• Application of Wind Fetch and Wave Models for Habitat Rehabilitation and Enhancement Projects - ArcGIS 10 Update
• Acadia National Park Mount Desert Island Landscape-Scale Ecological Assessment for Conservation Planning
• LINK: ArcGIS Tools for Conservation Planning
• Submersed Aquatic Vegetation Modeling Output Online
• U.S. Fish and Wildlife Service, National Wildlife Refuge System Water Resource Inventory and Assessment
