About the course
The DPhil in Population Health is a doctoral research programme intended to provide you with training in research, an in-depth knowledge and understanding of your doctoral research topic and will prepare you for a career in academia.
Research training will primarily be through day-to-day involvement in a research project and working with a research team. Research projects that students have worked on include ‘Can routinely collected data be used to accurately and completely follow-up participants in large randomised trials?’ and ‘Biological Ageing: Statistical analysis of physical and biochemical biomarkers in UK Biobank’. A typical day of a DPhil student varies through the course but will include literature reviews, data analysis, discussion with the research group and writing-up the research thesis.
Your supervisors will be the main source of your research training; you will also be encouraged to strengthen your research skills by taking relevant training courses. Research training will be within a multidisciplinary research environment which includes epidemiology, statistics, ethics, health economics, health promotion, health services research, and big data.
You will be encouraged to make use of the range of skills training offered by the Medical Sciences Division and the department throughout your study at the Nuffield Department of Population Health (NDPH). All students will be asked to complete a Training Needs Analysis (TNA) in the first term of your studies, which will be used to help students to assess their skill level and identify training required. There is no set period of time that should be used for training – students will be able to pursue the training they need. This training includes statistics, epidemiology, data management, research ethics, writing academic papers and presentation skills. You are also expected to identify additional relevant external courses that will support your research training.
Further information about part-time study
A small number of part-time students may be admitted to the DPhil in Population Health. Candidates applying for admission to this part-time course are required to show that their DPhil research topic is suited to part-time study and the supervisors agree with the part-time schedule. The in-residence attendance requirement will be a minimum of 30 days University-based work per year. This will be spread across the academic year with a minimum of ten days based in the department each term. However, attendance is likely to be higher and will be determined by the demands of the individual DPhil research project.
As a part-time student you will be required to attend supervision meetings and other obligations in Oxford for a minimum of 30 days each year. There will be limited flexibility in the dates of attendance, which will be determined by mutual agreement with your supervisor. You will have the opportunity to tailor your part-time study in liaison with your supervisor and agree your pattern of attendance.
The allocation of graduate supervision for this course is the responsibility of the Nuffield Department of Population Health and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff. In some circumstances a supervisor may be found outside the Nuffield Department of Population Health. Each student will be supervised by at least two supervisors. If one supervisor is from outside the department, a second supervisor will be appointed from within the department.
A supervisor should meet with their student regularly across the year. Once every two weeks during term time is indicative but is subject to individual arrangements.
All students will be admitted to the status of Probationer Research Student (PRS). Within a maximum of four terms as a full-time PRS student or eight terms as a part-time PRS student, you will be expected to apply for transfer of status from PRS to DPhil status.
Students who are successful at transfer will also be expected to apply for and gain confirmation of DPhil status to show that their work continues to be on track. This will need to be done within nine terms of admission for full-time students and eighteen terms of admission for part-time students.
Both milestones require an oral assessment with two assessors and therefore provide important experience for the final oral examination.
You will be expected to submit an original thesis after three years for full-time students and six years for part-time students. To be successfully awarded a DPhil in Population Health, your will need to defend your thesis orally (viva voce) in front of two appointed examiners.
Most DPhil alumni progress to academic posts both in the UK and Overseas, while others join health-related professions working for notable organisations such as the WHO and Public Health England.
Changes to this course and your supervision
The University will seek to deliver this course in accordance with the description set out in this course page. However, there may be situations in which it is desirable or necessary for the University to make changes in course provision, either before or after registration. The safety of students, staff and visitors is paramount and major changes to delivery or services may have to be made in circumstances of a pandemic, epidemic or local health emergency. In addition, in certain circumstances, for example due to visa difficulties or because the health needs of students cannot be met, it may be necessary to make adjustments to course requirements for international study.
Where possible your academic supervisor will not change for the duration of your course. However, it may be necessary to assign a new academic supervisor during the course of study or before registration for reasons which might include illness, sabbatical leave, parental leave or change in employment.

Information about course fees
Course fees are payable each year, for the duration of your fee liability (your fee liability is the length of time for which you are required to pay course fees). For courses lasting longer than one year, please be aware that fees will usually increase annually. For details, please see our guidance on changes to fees and charges.
Course fees cover your teaching as well as other academic services and facilities provided to support your studies. Unless specified in the additional information section below, course fees do not cover your accommodation, residential costs or other living costs. They also don’t cover any additional costs and charges that are outlined in the additional information below.
There are no compulsory elements of this course that entail additional costs beyond fees (or, after fee liability ends, continuation charges) and living costs. However, please note that, depending on your choice of research topic and the research required to complete it, you may incur additional expenses, such as travel expenses, research expenses, and field trips. You will need to meet these additional costs, although you may be able to apply for small grants from your department and/or college to help you cover some of these expenses.
Please note that you are required to attend in Oxford for a minimum of 30 days each year, and you may incur additional travel and accommodation expenses for this. Also, depending on your choice of research topic and the research required to complete it, you may incur further additional expenses, such as travel expenses, research expenses, and field trips. You will need to meet these additional costs, although you may be able to apply for small grants from your department and/or college to help you cover some of these expenses
In addition to your course fees, you will need to ensure that you have adequate funds to support your living costs for the duration of your course.
For the 2024-25 academic year, the range of likely living costs for full-time study is between c. £1,345 and £1,955 for each month spent in Oxford. Full information, including a breakdown of likely living costs in Oxford for items such as food, accommodation and study costs, is available on our living costs page. The current economic climate and high national rate of inflation make it very hard to estimate potential changes to the cost of living over the next few years. When planning your finances for any future years of study in Oxford beyond 2024-25, it is suggested that you allow for potential increases in living expenses of around 5% each year – although this rate may vary depending on the national economic situation. UK inflationary increases will be kept under review and this page updated.
If you are studying part-time your living costs may vary depending on your personal circumstances but you must still ensure that you will have sufficient funding to meet these costs for the duration of your course.
Students enrolled on this course will belong to both a department/faculty and a college. Please note that ‘college’ and ‘colleges’ refers to all 43 of the University’s colleges, including those designated as societies and permanent private halls (PPHs).
