This research tackles concrete’s carbon footprint by replacing Portland cement with locally sourced natural pozzolans. By calcining and testing South Island geomaterials, the work demonstrates a low-cost, carbon-free alternative that maintains strength and durability while reducing emissions and construction costs.

This research develops an algorithmic framework to proactively bundle small transportation projects, increasing contractor competition and reducing costs. Using a decade of Tennessee DOT data, it identifies optimal project groupings and flags combinations that reduce efficiency. Bundling improves value for agencies, contractors, and taxpayers, addressing significant waste in current procurement systems.

My research uses particle-based Discrete Element Modelling (DEM) to simulate and analyse how masonry structures age, crack, and fail. By accurately replicating real-life damage and strength, DEM provides a powerful tool for predicting deterioration, improving safety, and planning repairs without harming the structure. Future work explores mortar–brick interfaces, joint types, and brick geometry.
