Areas of Interest:

I use remote sensing and geospatial approaches to analyze patterns of social and ecological processes that drive landscape changes affecting earth's resources. My current research focuses on analyzing ecosystem structure and function and examining changes over space and time, particularly in response to natural and human disturbances. This information will help support my ultimate goal of mapping, quantifying, and valuing ecosystem services.

My areas of expertise include: remote sensing, LiDAR data analysis, image classification, object-based image analysis (OBIA), landscape change analysis, geospatial analysis, forest ecology (structure and function), human ecology mapping, air pollution effects on forest ecosystems, dendroecology.
