The degree of Doctor of Philosophy involves extensive, sustained and original research and study in a subject of your choice, with the results being presented in a thesis which will contribute to intellectual knowledge of the field. It is normally the highest academic qualification available and is a mark of intellectual ability, self-discipline and commitment. A PhD prepares you for an academic career in your chosen subject, and also many other career paths. The thesis must meet recognised international standards and presents the outcome of the research, placing it in the broader framework of the discipline or field of study. Carried out under qualified supervision, study towards a PhD promotes intellectual independence and the capacity to embark on further research at an advanced level.
