D.Eng Geosystems Engineering (Chiba University, Japan)

MSc(Eng) Geomatics (University of Cape Town, South Africa)

BSc(Hons) Surveying & Photogrammetry (University of Nairobi, Kenya)

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 International Society of Photogrammetry and Remote Sensing (ISPRS) and is a registered Associate Member of the Institution of Surveyors of Kenya (AMISK). He is currently an Associate Editor with the The International Journal of Applied Earth Observation and Geoinformation, and also serves in the International Cartographic Association (ICA) under the Commission on Sensor-driven Mapping. Professor Ouma's recent research projects are focused on the development of:

1. innovative Earth Observation Analytics and AI-based algorithms and methods for modelling long-term impacts of climate change and anthropogenic activities on water quality and water quantity in semi-arid regions, with current case study of Botswana's Limpopo River Basin;
2. low-cost sensor-driven mobile mapping systems and solutions for modelling of water quality and road pavement conditions;
3. 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.
