About the course
The Departments of Plant Sciences and Zoology are merging in 2022 to create a new Department of Biology, offering a broad range of research opportunities for graduate students. The departments maintain a large and interactive group of around 200 DPhil students.
As a doctoral student, your primary focus will be your research, which will usually 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 supervisor(s) 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. The department also provides training to all DPhil students that focuses on developing both research and professional skills.
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 vast 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 departments have 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 departments' research community and their work is showcased annually at the departmental Graduate Symposium.
The allocation of graduate supervision for this course is the responsibility of the Department of Plant Sciences and the Department of Zoology 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 Plant Sciences and the Department of Zoology.
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. You will typically meet with your supervisor weekly or fortnightly to discuss your progress and developments in the field, although this may vary depending on the area of research, the nature of your project, and the stage of your studies.
If you are studying part-time, it is likely that you will meet your supervisor less frequently.
All students will be initially admitted to the status of Probationer Research Student (PRS). Within a maximum of six terms as a full-time PRS student or twelve terms as a part-time 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 for full-time students and by the eighth term for part-time students.
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 for full-time students and eighteen terms of admission for part-time students.
Both milestones normally involve an interview with two assessors (other than your supervisor) and therefore provide important experience for the final oral examination.
Full-time 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. If you are studying part-time, you be required to submit your thesis after six or, at most, eight 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.
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 in circumstances of a pandemic (including Covid-19), 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.
