My teaching and research have a focus on the application of spatial technologies, satellite imagery and ground based GIS data layers for environmental modelling, and covers areas such as: Climate change impacts on small island states in the Pacific and the Himalayan region Species Distribution Modelling in investigating the impacts of climate change and weeds on endemic biodiversity Climate change impacts on agricultural productivity and land suitability Remote Sensing of invasive weed species Ecological Remote Sensing, with emphasis on vegetation pattern analysis and monitoring, agricultural land use mapping as well as wildlife habitat evaluation Spectral discrimination of vegetation species and biodiversity assessment using hyperspectral remote sensing
