  • Data-Mining and Machine-Learning

Research Vision & Interests:

My area of research is in pedometrics鈥攁 branch of soil science that aims to develop accurate and precise high resolution digital soil maps and predictive models that provide knowledge of soil variability over space and time. This discipline is the convergence of soil science, applied computing science, and remote sensing by leveraging the advances in geographical information systems, machine-learning, artificial intelligence, and Big Data analytics. At the Soil-Landscapes Analysis and Modelling Lab, my team focusses on the modeling and monitoring of soil properties and health, assessment of soil functions, and the transformation of soil data into knowledge to support decision making processes across diverse spatial scales. Spatial soil information and estimates of uncertainty are critical towards informing sustainable soil resource management practices and successfully implementing nature-based solutions to climate change. At the local-scale, I contribute data for precision agriculture, on-farm carbon sequestration programs and enhanced forest resource inventory activities. At the national-scale, my team supports the reporting of greenhouse gas emissions by providing baseline soil data for informing national- and global climate change models, ensuring that our international commitments to monitor, verify, and report on the state of our soil resources are met.
