My Research Interests

My research focuses on remote sensing techniques, geospatial analysis, and ecosystem modelling of natural or managed systems. My approach exploits observation windows at various spatial and temporal scales to investigate the linkages between changes in plant biophysical and biochemical traits in relation to environmental and anthropogenic driving factors. This work has been supported by major grants from various internal and external sources, including NSERC, CFI, ERA, et al.

I participate in the following research clusters:

Geospatial Systems & Geomatics
Environmental Processes & Change in Natural Systems
Human-Environment Interactions

Graduate Student Recruitment

Fully-funded MSc and Ph.D. positions are available at my Remote Sensing and Spatial Ecosystem Modeling laboratory (the RSSEM Lab). Candidates will develop new techniques for quantifying vegetation stress using the latest remote sensing technology. Some of the data will be collected using unmanned aerial vehicles or helicopters carrying hyperspectral sensors, multispectral sensors, as well as thermal sensors. I look for students with the following qualifications: 1) sincere interest in remote sensing and vegetation ecology; 2) strong quantitative skills; 3) remote sensing skills, or the ability to learn them quickly; and 4) excellent oral and written communication skills in English. Applicants should send me a letter of enquiry and curriculum vitae.
