The structure of a PhD thesis typically includes several key components. It starts with a **title page**, followed by an **abstract** summarizing the research. The **introduction** outlines the research problem, objectives, and significance. The **literature review** surveys relevant existing research. The **methodology** section describes the research design and methods used. **Results** present the findings, while the **discussion** interprets these results in context. The **conclusion** summarizes the research and suggests future work. Finally, include a **bibliography** and **appendices** for supplementary material.
