DPhil in Biology
About the course
The Department of Biology offers a broad range of research opportunities for graduate students. The department maintains a large and interactive group of around 200 DPhil students.
As a doctoral student, your primary focus will be your research, which will be conducted within one or more of the existing research groups. You will be expected to develop an original research project under the guidance of your academic supervisors and normally on a topic related to their areas of expertise. In addition, you will be encouraged to make the most of the doctoral training and research methods provision available across the Mathematical, Physical and Life Sciences Division.
Doctoral research projects can be based on fieldwork (sometimes in remote places), laboratory experiments, analysis of existing data sets, or mathematical theory, but in all cases must be original and rigorous, leading to publications in peer-reviewed scientific journals. The majority of your time will, therefore, be spent in independent self-directed research and will involve a mixture of experimental, computational and observational activities.
You will be part of a vibrant educational research community that includes an active set of doctoral student-led events, seminars and workshops. You will have the opportunity to present and discuss your work in progress with your supervisor, other faculty members and peers, informally day-to-day and by attending a variety of seminars and workshops in the department and at conferences elsewhere.
The department has a friendly graduate community which provides a welcoming network to new students. The graduate student community offers a supportive environment, both social and scientific, allowing new graduates to develop into well-rounded and confident scientists. Graduates are a valued part of the department's research community and their work is showcased annually at the departmental Graduate Symposium.
Attendance
The course is full-time and requires attendance in Oxford. Full-time students are subject to the University's Residence requirements.
Provision exists for students on some courses to undertake their research in a ‘well-founded laboratory’ outside of the University. This may require travel to and attendance at a site that is not located in Oxford. Where known, existing collaborations will be outlined on this page. Please read the course information carefully, including the additional information about course fees and costs.
Resources to support your study
As a graduate student, you will have access to the University's wide range of world-class resources including libraries, museums, galleries, digital resources and IT services.
The Bodleian Libraries is the largest library system in the UK. It includes the main Bodleian Library and libraries across Oxford, including major research libraries and faculty, department and institute libraries. Together, the Libraries hold more than 13 million printed items, provide access to e-journals, and contain outstanding special collections including rare books and manuscripts, classical papyri, maps, music, art and printed ephemera.
The University's IT Services is available to all students to support with core university IT systems and tools, as well as many other services and facilities. IT Services also offers a range of IT learning courses for students, to support with learning and research.
The Department of Biology offers students access to desk space, research laboratories, and field research facilities. Most students will be based in the Life and Mind Building, but some research groups are based at the Peter Medawar Building for Pathogen Research, the John Krebs Field Station, or the Wildlife Conservation Research Unit. Many groups in the department also conduct research at field sites in the UK and overseas.
Supervision
The allocation of graduate supervision for this course is the responsibility of the Department of Biology and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff. Under exceptional circumstances, a supervisor may be found outside the Department of Biology.
As a graduate student you will be embedded in the research groups of two or more members of academic staff who act as your supervisors and provide the bulk of the research guidance and training.
Most students have the opportunity to meet with their supervisor weekly or fortnightly to discuss their progress and developments in the field. However, this frequency may vary depending on the area of research, the nature of your project, and the stage of your studies.
Assessment
All students will be initially admitted to the status of Probationer Research Student (PRS). Within a maximum of six terms as a PRS student, you will be expected to apply for transfer of status from Probationer Research Student to DPhil status. This application is normally made by the fourth term.
A successful transfer of status from PRS to DPhil status will require a report that will consist of an introductory part that could become the introduction to the thesis, one rather well-worked analysis of preliminary data representing roughly the equivalent of one thesis chapter, and a plan for the other chapters in the thesis including a detailed timetable. Students who are successful at transfer will also be expected to apply for and gain confirmation of DPhil status to show that your work continues to be on track. This will need to done within nine terms of admission.
Both milestones normally involve an interview with two assessors (other than your supervisor) and therefore provide important experience for the final oral examination.
Students will be expected to submit a substantial thesis of up to 50,000 words after three or, at most, four years from the date of admission. To be successfully awarded a DPhil in Biology you will need to defend your thesis orally (viva voce) in front of two appointed examiners.
Graduate destinations
The DPhil in Biology is a new course, replacing the DPhil in Plant Sciences and the DPhil in Zoology.
100% of alumni from the DPhil in Plant Sciences are employed, across a wide range of sectors, with 60% working in academic research positions. The department retains contact with its alumni to find out what they have gone on to do after completing their course. Past students from the Department of Plant Sciences have gone on to careers both in the UK and other countries in teaching and research in schools, universities, policy for government departments, industry, and administration at local and national levels.
Zoology graduates, like DPhil graduates in biological sciences at Oxford as a whole, continue to a wide range of careers after graduating. Between 2012 and 2017, 83% of DPhil graduates continued in bioscience-related posts, of which almost three quarters involved academic research.
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 if a pandemic, epidemic or local health emergency occurs. 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.
For further information please see our page on changes to courses and the provisions of the student contract regarding changes to courses.

Biology
The Department of Biology is one of the leading UK university departments dedicated to research and teaching in biology, possessing world-class strengths across the breadth of modern biological science research.
The department’s research is organised into five sections:
- Behaviour and Biomechanics
- Ecology and Evolution
- Evolution and Developmental Biology
- Microbiology and Infectious Disease
- Molecular Plant Biology
There is considerable overlap between these sections, with many members of the department working in more than one section, and many research projects that cut across section boundaries. Indeed, a key characteristic of the department is that it works as a well-integrated whole with collaborations developing naturally between researchers working on diverse topics.
The Department of Biology has research strengths spanning from evolution to ecology, behaviour to biomechanics, and development to disease. Researchers in the department work on wide range of organisms, including plants, animals and microbes. This diversity of research interests is reflected in the wide range of research facilities that are used by members of the department, including labs that are for cell and molecular biology, controlled growth facilities, field stations, and unique plant collections. Many of our students also carry out field work at in locations ranging from the Amazon rainforest to the Antarctic.
Within the department are several research institutes, including the Edward Grey Institute (EGI), the Wildlife Conservation Research Unit (WildCRU) , the Interdisciplinary Centre for Conservation Science (ICCS), and the Ineos Oxford Institute for Antimicrobial Research (IOI).
In 2025, the Department of Biology plans to move into the new Life and Mind Building. The Life and Mind Building will transform the education experience for students, providing new laboratories and meeting spaces for undergraduates, postgraduates and researchers, as well as lecture theatres, specialised support laboratories and opportunities for public engagement with our research. It will be the largest building project the University has ever undertaken and will be a catalyst for the advancement of psychological and biological science both at the University of Oxford and on a global platform.
There are two routes into undertaking your doctoral research at the department. You may apply directly to the DPhil in Biology. Alternatively, you may apply to one of the University’s Doctoral Training Programmes. The latter are fully-funded, four-year graduate training programmes which involve a training period of taught courses for around three to six months before deciding on a DPhil project. Applicants are encouraged to consider both entry routes.
Funding
For entry in the 2025-26 academic year, the collegiate University expects to offer over 1,000 full or partial graduate scholarships across a wide range of graduate courses.
If you apply by the January deadline shown on this page and receive a course offer, your application will then be considered for Oxford scholarships. For the majority of Oxford scholarships, your application will automatically be assessed against the eligibility criteria, without needing to make a separate application. There are further Oxford scholarships available which have additional eligibility criteria and where you are required to submit a separate application. Most scholarships are awarded on the basis of academic merit and/or potential.
To ensure that you are considered for Oxford scholarships that require a separate application, for which you may be eligible, use our fees, funding and scholarship search tool to identify these opportunities and find out how to apply. Alongside Oxford scholarships, you should also consider other opportunities for which you may be eligible including a range of external funding, loan schemes for postgraduate study and any other scholarships which may also still be available after the January deadline as listed on our fees, funding and scholarship search tool.
Details of college-specific funding opportunities can also be found on individual college websites:
Please refer to the College preference section of this page to identify which of the colleges listed above accept students for this course.
For the majority of college scholarships, it doesn’t matter which college, if any, you state a preference for in your application. If another college is able to offer you a scholarship, your application can be moved to that college if you accept the scholarship. Some college scholarships may require you to state a preference for that college when you apply, so check the eligibility requirements carefully.
Further information about funding opportunities for this course can be found on the department's website.

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.
Continuation charges
Following the period of fee liability, you may also be required to pay a University continuation charge and a college continuation charge. The University and college continuation charges are shown on the Continuation charges page.
Where can I find further information about fees?
The Fees and Funding section of this website provides further information about course fees, including information about fee status and eligibility and your length of fee liability.
Additional information
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.
Living costs
In addition to your course fees and any additional course-specific costs, you will need to ensure that you have adequate funds to support your living costs for the duration of your course.
Living costs for full-time study
For the 2025-26 academic year, the range of likely living costs for a single, full-time student is between £1,425 and £2,035 for each month spent in Oxford. We provide the cost per month so you can multiply up by the number of months you expect to live in Oxford. Depending on your circumstances, you may also need to budget for the costs of a student visa and immigration health surcharge and/or living costs for family members or other dependants that you plan to bring with you to Oxford (assuming that dependant visa eligibility criteria are met).
Further information about living costs
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. For study in Oxford beyond the 2025-26 academic year, it is suggested that you budget for potential increases in living expenses of around 4% each year – although this rate may vary depending on the national economic situation. For further information, please consult our more detailed information about living costs, which includes a breakdown of likely living costs in Oxford for items such as food, accommodation and study costs.
