My research area is remote sensing of forest environments that includes aspects of landscape disturbance ecology and advanced spatial analysis. For the past 23 years at the Maine Image Analysis Laboratory, my students and I have been using satellite imagery, aerial photography and GIS to map, measure and monitor changes in New England and tropical Central American forests. In Maine, we are mapping forest disturbance and regeneration composition, patterns and trends using Landsat imagery from 1972 to present. We are working with wildlife researchers to track changes and model wildlife habitat structure for Canada lynx and American marten, and with state agencies and conservation organizations to monitor forest changes and landscape metrics as indicators of biodiversity on large conservation easements.

Before coming to Maine I was a research forester for NASA Stennis Space Center, MS and a remote sensing analyst at the Bureau of Land Management, Branch of Remote Sensing in Denver, CO, conducting rangeland mapping projects in 7 western states.
