Doctor of Philosophy

Science

The degree of Doctor of Philosophy is a University degree governed by the University of Sydney (Higher Degree by Research) Rule 2026. Candidates should be familiar with this Rule and other associated policies and procedures relevant to this degree and can be accessed via the University Policy Register.

The degree of Doctor of Philosophy is a research degree awarded for a thesis considered to be a substantially original contribution to the subject concerned. 

Applicants should normally hold a master's degree with research or a bachelor's degree with first or high second-class honours of the University of Sydney, or an equivalent qualification from another university or institution.

The degree may be taken on either a full-time or part-time basis. The first full year of candidature is normally on probation. The minimum period of candidature is three years. In the case of full-time candidates the maximum period of candidature is normally three and a half years, and the maximum period of candidature for part-time candidatures is 8 years, although it should be noted that the maximum is dependent on the proportion of full-time and part-time enrolment.

Part-time candidature may be approved for applicants who can demonstrate that they are engaged in an occupation or other activity which leaves them substantially free to pursue their candidature for the degree. They should be able to devote at least 20 hours per week to candidature or an equivalent annual period made up in blocks.
