- Integrated multi-source geospatial datasets (CHIRPS, SoilGrids, MODIS) using Google Earth Engine to construct a harmonised sub-national dataset across 11 sub-counties in Kenya - Developed and evaluated multiple ML models (Random Forest, Ridge, LASSO, SVM, GBM) to analyse environmental drivers of maize yield - Key predictors identified: maximum temperature (Tmax in March/May), soil water saturation (SSAT), and NDVI during the growing season — consistent across linear and non-linear models - Applied PCA-bas

- Processed hyperspectral field imagery in QGIS, including GeoTIFF conversion, georeferencing, and spectral correction across experimental plots with varying nitrogen treatments - Extracted vegetation spectral signatures and calculated reflectance-based indices (CVI, Green–Red ratio) to characterize plant responses under different conditions - Applied unsupervised clustering (SCP plugin) to differentiate vegetation responses across treatment groups - Validated spectral indices against laboratory-measured le

- Sustainable Design Consulting for USGBC-Certified Green Building Projects: Contributing expertise to over 15 green building projects certified by the U.S. Green Building Council in Asia. - Enforced Green Building Compliance: Collaborated with architects and contractors to ensure strict compliance with USGBC regulations from design to construction. - Water efficiency and biodiversity data collection and analysis - Certification documentation preparation and technical review oversight - Research green build

- Facilitated lectures and workshops. - Prepared course modules include Location & Transportation, Sustainable Sites, Water Efficiency, Material & Resources.

- Coordinated different working groups within OPIRG and designed posters, e-newsletters to promote events. - Organized documentary night and open-mic night for public participation in social issues.

Coursework completed 2021. Thesis conducted 2024–2025 (grade 1.0) on ML-based maize yield prediction in Kenya.
