Research
Successfully conducting tests and analyse environmental data to determine the impact of human activities on the environment has been my ambition. I used hydrological modelling and geospatial analysis to understand the seasonal and interannual movement of water and sediments in the fact of land use and climate changes, utilising spatial tools and hydrological models. I have diverse research interest comprising of surface hydrological modelling, geo-hydrological modelling, surface and groundwater interaction modelling, climate, land use and soil change impact studies, mining impact studies, and land cover change detection and scaling.
