A doctoral thesis is an extensive and original research document that presents the author's findings and contributions to knowledge in their field of study, demonstrating their expertise and ability to conduct independent research.

Organizing the vast and intricate knowledge accumulated during a PhD into a cohesive and comprehensive thesis is a monumental challenge that demands exceptional focus, clarity, and perseverance. 

Have a look at this thesis structure. The structure is quite simple, traditional (and bland?), but in my experience is the best structure for getting the job done. This works for both Masters and PhD level works. 

All the best, and please share with whomever you feel it will be useful!
