Research and Professional Interests

Thesis: Long-term remote sensing for monitoring forest change across a suburbanizing landscape

My research involves using high and moderate resolution remote sensing platforms (e.g., aerial photography, Landsat) to monitor long-term rural and urban forest change (i.e., since the mid-1900s) in a southern Ontario landscape that has undergone extensive suburban development. This remote sensing analysis is supported by extensive field data, including dendrochronology (i.e., tree rings) and ground validation of canopy cover (i.e., hemispherical photography, aerial photograph interpretation). Monitoring includes understanding social changes (e.g., historical inequalities in urban forest canopy distribution) and environmental changes (e.g., gradual and abrupt disturbances in forest canopies).

Why Geography, Geomatics and Environment at UTM?

I chose UTM for my Ph.D. because of its top-of-the-line facilities, great financial support, and quality professors who can contribute to my research.
