Early Design Stage Building Lifecycle Analysis (LCA) of Cost & Carbon Impact
In my research, I have developed a building lifecycle analysis (LCA) workflow that recommends sustainable solutions based on the optimization of building lifecycle cost ($) and carbon impact (kgCO2eq). The workflow can analyze conceptual geometries in the early design stage when there is limited …

Scenario based lifecycle analysis of greenhouse gas emissions from petroleum-derived transportation fuels in 2050
… associated with the entire petroleum fuel lifecycle. Although the current non-combustion production lifecycle emissions of these fuels are well understood, their future lifecycle emissions have yet to be quantified. In this thesis, a global, scenario-based analysis of petroleum-derived …

A roadmap for net-zero energy buildings in emerging economies: a study of residential new-buildings in Nigeria
… the qualitative data was analysed using thematic analysis. Based on the research findings, a strategic roadmap with timelines and milestones was developed to achieve NZEBs within the residential sector in Nigeria. The nature of this roadmap involves policy creation and implementation, regulatory …

A system theoretic approach to cybersecurity risks analysis of passenger autonomous vehicles
… Traditional methods treat safety and security analysis in isolation, and are limited in the ability to account for interactions among organizational, socio-technical, human, and technical components. In response to these challenges, the System Theoretic Process Analysis (STPA) was developed to …
