My research and teaching is focused on remote sensing digital image processing, GIS, and statistical modelling. I develop advanced image classification algorithms to improve land cover mapping accuracy and monitor land cover change. My image processing algorithms rely heavily on machine learning and target near real-time monitoring. In addition to remote sensing image processing, I study land change patterns and processes using spatial statistical models. I am particularly interested in understanding the drivers and consequences of land cover change. I integrate land change simulation model and ecohydrological models to address these broad questions.
