Research Interests

• Development of remote sensing and advanced computing methods for mapping and characterizing terrestrial change
• The causes and consequences of land use change and fire in Southern Africa
• Methodologies to facilitate the transfer of remote sensing products into the user domain, for example by facilitating regional networks such as the Southern Africa Fire Network (SAFNet)
• Quality assessment of moderate spatial resolution terrestrial remote sensing products

• Burned area mapping in southern Africa: case study synthesis and regional application of MODIS data
• A Study of the Development of Remote Sensing Algorithms with Emphasis on Using the MODIS Instrument for Land Science Research
• Data Analysis Tools for the MODIS Land User Community
