Yashon Ouma is a Professor of Geomatics, with more than 20 years of experience in research and teaching. Yashon is an Alexander von Humboldt (AvH) Experienced Research Fellow with research/work experience in South Africa, Germany, Kenya, Japan and Botswana. Professionally, Professor Ouma is a member of the ISPRS and is a registered Associate Member of the Institution of Surveyors of Kenya (AMISK). He is currently Co-Chair of the Technical Advisory Committe of Digital Earth Africa, Associate Editor of the International Journal of Applied Earth Observation & Geoinformation, serves in the International Cartographic Association (ICA) - Commission on Sensor driven Mapping and the ICA Commission on GeoAI. Professor Ouma's recent research projects are focused on the development of:
- Innovative UAV & Satellite based Earth Observation Data Analytics and AI-based algorithms and methods for modelling long-term impacts of Anthropocene and Climate Change on water quality and water quantity.
- Low-cost sensor-driven mobile mapping systems and solutions for modelling of water quality and road pavement conditions.
- Multisensor remote sensing approaches for understanding urban growth dynamics and impacts of urban expansion, including land-use and land-cover change detection and Land Surface Temperature (LST) dynamics.
