Research Interests

I am interested in studying how human practices impact ecological systems. More specifically, I examine land use and land cover changes and how these changes may be linked to nitrate contamination. Using a landscape mapping perspective, I am working to determine what terrestrial landscape indicators correlate best with and predict groundwater nitrate levels in the Abbotsford – Sumas Aquifer, a region that spans the US-Canada border (between SW British Columbia and Washington).  I use high spatial resolution imagery (i.e. LiDAR, RapidEye, historical aerial photos) to quantify fine scale features with suspected mechanistic links to nitrate sources. This work represents an important first step in the development of affordable monitoring approaches for trans-border water resources.
