ABOUT ME

Education

  • MSc Candidate – University of Toronto
  • HBSc Environmental Science, Earth Science and GIS – University of Toronto Mississauga

Research and Professional Interests

My current research interests include environmental science, remote sensing, GIS, conservation and resource management. My Master’s research focuses on the use of airborne hyperspectral remote sensing to detect insect disturbances in forests. The Emerald Ash Borer (EAB) is an invasive insect that has caused widespread mortality of native ash species throughout North America.  My research combines very high spatial and spectral resolution imagery, geospatial data, biophysical and biochemical data, and quantifies changes in vegetation health related to insect infestations. I am working to improve remote sensing detection methods and models that can be used to accurately detect disturbances. This research will contribute to our knowledge of the effects of EAB on ash trees in local ecosystems and the development of cutting-edge monitoring practices.

My professional interests align with my research interests. I have worked at various Ministries including the Ontario Ministry of Natural Resources in Peterborough, ON, and the Ontario Ministry of the Environment in Toronto, ON, where I was involved in a variety of operational remote sensing projects, such as a provincial vegetation phenology project and a near real-time flood monitoring program.

Why Geography at UTM?

Geography at UTM harbours a diverse group of researchers and subdisciplines, and has great facilities and support to conduct high-quality research. I am currently working under the supervision of Dr. Yuhong He in the Remote Sensing and Spatial Ecosystems Modelling Lab (RSSEM), where I have access and support to use a variety of remote sensing instruments and lab facilities to conduct my research. My lab group is very supportive, innovative and enthusiastic and a great group to work alongside. Furthermore, UTM is a great campus and has a great community.
