Research Scientist

My research develops methods, models and algorithms to monitor the state and condition of our soils and crops using data from multi-spectral, hyperspectral and Synthetic Aperture Radar (SAR) satellites.

Current research and/or projects

I am currently leading two research projects:

“An International Comparison Of Synthetic Aperture Radar (SAR) Based Methods For Crop Type And Crop Condition Monitoring: Developing An Operational Monitoring Capability For Canada, And Beyond” 

"Quantifying Crop Productivity from Space: A New Radar Satellite-based​ Metric for Measuring Crop Response"
