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 JournalÌýof Applied Earth Observation & Geoinformation, serves inÌýthe International CartographicÌýAssociation (ICA) - Commission onÌýSensor drivenÌýMapping and the ICA Commission on GeoAI.ÌýProfessor Ouma's recent research projects are focused on the development of:

1. Innovative UAV & Satellite based Earth Observation Data Analytics and AI-based algorithms and methodsÌýfor modellingÌýlong-term impacts ofÌýAnthropocene and Climate Change on water quality and waterÌýquantity.
2. Low-cost sensor-driven mobile mapping systems and solutions for modelling of water quality and road pavementÌýconditions.
3. Multisensor remote sensing approaches forÌýunderstanding urban growth dynamics and impacts of urban expansion, including land-use and land-cover change detection and Land Surface Temperature (LST) dynamics.
