Numerous opportunities for research studies leading to Doctor of Philosophy (PhD) degree. Under our outcome-based framework, research students pursue a series of compulsory and elective subjects in depth, with a view to contributing to the existing body of knowledge, as well as a research project under the supervision of an experienced academic staff member with similar research interests.

PhD students must satisfactorily investigate or evaluate a chosen area, demonstrate an understanding of the context and significance of the work, display sustained independent effort and original thought and present a clear, complete thesis of a quality worthy of publication.

The PhD degree is awarded to students who, on completion of an approved programme of study and research, present a thesis that embodies the results of their research and satisfy the examiners in an oral examination in matters relevant to the subject of the thesis. Students must also complete the coursework requirement before submitting their theses. The subjects are chosen by the student, with advice from the supervisor, from a wide range on offer.

Course Structure:

Three years (for students admitted on the basis of a Master's degree with a significant research component);
Four years (for students admitted on the basis of a Master's degree or a Bachelor's degree)

Entry requirements

For students from United States

For admission to a Doctoral degree programme, you must possess a Master's degree. A Test of English as a Foreign Language (TOEFL) score of 80 for the Internet based test or 550 for the paper-based test; OR An overall Band Score of at least 6 in the International English Language Testing System (IELTS).

For international students

To register for the degree of PhD, a student must normally hold a postgraduate degree containing a significant research component, such as a dissertation, conferred by a recognized university.

In exceptional circumstances, applicants other than those stipulated above may be admitted directly to the PhD programme. For example, an applicant with a Bachelor’s degree with First Class Honours, or the equivalent. Such applicants may be required to pass an examination.

PolyU may accept other equivalent qualifications. The decision is made on an individual basis.

English Language Requirements

The requirements for those who do not have a degree for which English was the language of instruction at a recognised university are:

An overall score of at least 6.5 (with score for the writing component at 6.0 or above) in the International English Language Testing System (IELTS); OR

A Test of English as a Foreign Language (TOEFL) score of 80 or above for the Internet-based test (with a writing score of 23 or above) or 550 or above for the paper-based test (with a score of 4 or above in the Test of Written English).

Alternatively, consideration will be given to acceptable scores in other internationally recognised public examinations, such as the Graduate Record Examination (GRE) or the Graduate Management Admission Test (GMAT).

*There may be different IELTS requirements depending on your chosen course.
