PhD Qualifying Examinations

Department Guidelines for Qualifying Examination(QE)

The PhD Qualifying Examination (QE) is compulsory for all postgraduate students who aim to complete their research-based graduate study under the PhD candidature that will lead to the award of the degree in Doctor of Philosophy degree upon completion of all requirements.

Purpose and Philosophy

The aims of the Graduate Study Program in Pharmacy (by research) are to train students to develop the following characteristics:

  • To acquire expert knowledge and technical competency in a specialized area of research;
  • To be able to critically analyze research problems, propose hypothesis/research question and suggest approaches to conduct the necessary investigation;
  • To be able to apply scientific methodologies for conducting properly designed experiments and generating relevant data, critically analyze research findings, provide an objective summary of results and a proposal for future investigations;
  • To be able to write and present their research findings in a concise, coherent and objective manner;
  • To be able to instruct and mentor junior students;
  • To acquire a mindset for workplace safety;
  • To exercise integrity and honesty in all research endeavors; and
  • To demonstrate the ability to think and conduct investigations across discipline boundaries.


The PhD Qualifying Examination has 2 main objectives:

  • To assess and ascertain that the graduate students are equipped with a strong foundation in the fundamental domain knowledge in his/her discipline of study.
  • To assess and ascertain that the graduate students have demonstrated the ability to conduct investigations, write and orally defend a sound research project proposal supported by relevant data.


The PhD Qualifying Examination consists of 2 parts: QE I and QE II


The aim of QE I is to assess the candidate’s fundamental domain knowledge in one of the four domains where his/her chosen laboratory is based. QE I is an one hour oral examination to be conducted by a panel of faculty members from the respective domain. 

Students are expected to be competent in their foundation knowledge pertaining to their own domain. Foundation knowledge in the respective domain is likely to be represented by topics covered in the following undergraduate modules offered by the department:

Module Code Module Title Module Coordinator Module Descriptions
PR1110 (for PC domain) Foundations for Medicinal Chemistry Assoc Prof Chui Wai Keung This module studies the fundamental physical & chemical principles that are important to the design and development of drugs. The major topics to be covered include: molecular properties, electronic effects, functional groups and heterocycle nomenclature, intermolecular forces, acidity & basicity, conformation and stereochemistry, tautomerism, solubility, lipophilicity and permeability.
PR1111 (for PB domain) Pharmaceutical Biochemistry Assoc Prof Chew Eng Hui This module is aimed to provide fundamental biochemistry knowledge which is important and relevant for pharmacy students to relate the knowledge to drug discovery and development. The module will emphasise the relevance and application of biochemistry in pharmaceutical and pharmacy practices.
PR2114 (for PT domain) Formulation & Technology I Assoc Prof Gigi Chiu This module studies the fundamental physical chemical principles which are important to the design and development of pharmaceutical formulations. The major topics to be covered include: phase diagrams; solutions; buffers & isotonicity; partition, diffusion & mass transfer; solubility & dissolution; reaction kinetics & drug product stability; physical properties of solids (crystallinity, polymorphism); interfacial phenomenon; colloidal systems.

  1. Each student will be examined by the panel of examiners for 1 hour.
  2. If the student fails QE I examination, he/she will be allowed to re-take the examination only one more time
  3. Each student taking the oral examination will be assessed individually for their ability in handling and answering questions in a logical and rational manner. Supervisors should NOT be present during the QE I examination.
  4. For students who have cross-disciplinary background, they are welcome to identify up to two domains for the oral examination, with one as a major domain. Panel members will be chosen to be able to conduct oral examination in both domains.
  5. Students are encouraged to sit for their QE I examination in their first semester, but must do so no later than the second semester in the program.
  6. Students must pass their QE I by the end of their 3rd semester to be eligible to sit for QE II at the end of their 4th semester.

Students in the PhD Programme must pass QE II by the end of their fourth semester to be eligible for advancing to Ph.D candidature.

  1. QE II consists of a written report, an open seminar and a closed door oral defence session based on the candidate’s research project proposal supported by relevant results. QE II is intended to assess the candidate’s ability to design, write and orally defend his/her research project proposal. The report and presentation will be assessed by two examiners.
  2. Graduate students can only apply to sit for Part II of the QE in their 3rd or 4th semester. He/she must also satisfy all of the following conditions to be eligible to sit for Part II of the QE:
    • Completed PR5198 and one level 5000 module on statistics
    • Completed at least two additional Level 5000 modules
    • Maintain overall CAP at 3.5 or above
    • Passed English language proficiency requirement (where applicable)
    • Passed QE I
    • Endorsement from supervisor and co-supervisor for taking the examination.
  3. Only one attempt in QE II is allowed. However, under exceptional circumstances, appeal to HOD may be permitted. In such instance, HOD, in consultation with the examiners, will decide whether to allow the student to re-take his/her QE2 one more time.
  4. Nomination of QE II examiners
  5. The following exclusion criteria apply when selecting suitable examiners for QE II:
    • Examiners must not be related (by family) to the candidate or the supervisor(s)
    • Examiners must not be the candidate’s research collaborator / co-author or have financial involvement in the research project
    • Examiners should not be co-authors with the supervisor(s) in the past 3 years
    • Examiners should not have been trained by the same supervisor as the candidate’s supervisor
    • The nominated examiner should not be previous research student (either FYP/PhD) of the supervisor(s) or vice-versa.
  6. Additional important considerations for selecting examiner for QE II:
    • Consent of the examiners proposed by the student’s supervisor must be obtained before nomination.
    • The list of proposed examiners should be approved by the Graduate Committee Domain Representative or Chair of Department Graduate Committee.
    • External examiners examining the report containing patentable/confidential materials will need to read and agree to the Terms & Conditions on the Non-Disclosure Agreement (NDA) before the report is sent to him/her (this also applies to examiners from NUH and NUHS).  Main Supervisor is required to arrange for the execution of the NDA for External Examiners.
