Recent research:
Across the publications, the research program advances sustainable water management, urban resilience, and materials-enabled infrastructure optimization. The work demonstrates practical ecological rainwater harvesting with green roofs to reduce potable water use and mitigate flooding in urban Ecuador, integrating hydrological analysis, vegetation selection, and properly sized conveyance to ensure water-quality and hydraulic efficiency for toilet flushing and fire response. It also presents transient unsteady-flow analysis in urban water networks to guarantee reliable supply under dynamic operations, using numerical HAMMER modeling to define safe operating times, design pressures, and protection against transient-induced damage, aligned with AWWA standards. In pavement engineering, the research explores recycled waste materials—tire rubber powder and blister-type PVC—in asphalt mixtures, comparing their effects on stability, flow, density, and void content; findings indicate PVC improves asphalt performance more notably than rubber powder, informing sustainable material substitution pathways. Collectively, the studies contribute to sustainable resource management, infrastructure reliability, and circular economy approaches in urban settings, with methods spanning hydrological design, numerical hydraulics, standards-compliant pressure analysis, and materials performance evaluation.
