DPhil in Earth Sciences
About the course
The Earth sciences are the focus of scientific understanding about this and other planets, embracing a large range of fundamental topics including the evolution of life, how climate has changed in the past and will change in the future, the nature of planetary surfaces and interiors and the processes underlying natural hazards like earthquakes and volcanoes.
The DPhil is an advanced degree by research that will take between three to four years to complete.
You will typically join a research group and work alongside other research students, postdoctoral researchers and academics all of whom provide additional support and advice for DPhil students. You will work alongside each other in the same general research area. Research themes in the department are:
- Geophysics and Geodynamics
- Planetary Evolution and Materials
- Oceanography, Climate and Palaeoenvironment
- Palaeobiology and Evolution
- Geodesy, Tectonics, Volcanology and Related Hazards
- Earth Resources
Academic activity across research groups is also strongly encouraged.
While the focus of the DPhil is on your development to conduct independent research, there are formal courses available both within the Department of Earth Sciences and other departments in the Maths, Physical and Life Sciences (MPLS) Division. Formal courses are organised through the MPLS Graduate Academic Programme and include generic skills such as advice on science writing, as well as subject specific specialist courses. These allow the structured course components to be tailored to your individual research project needs.
There are also paid opportunities for you to gain teaching experience by demonstrating laboratory classes to undergraduates, assisting on undergraduate fieldtrips or in tutorial teaching.
You will be encouraged to present your research at national and international meetings and publish in internationally-recognised science journals. You may also choose to take part in outreach activities, explaining to the public and schoolchildren the exciting science conducted in the department. Within the department you will be part of a community of seventy research students including students enrolled on the Environmental Research NERC Doctoral Training Partnership course.
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 Earth Sciences occupies a building specifically designed for the teaching and research needs of geoscientists. Whatever the area of the Earth sciences you have chosen to study at DPhil level, the specialist research facilities are world class. This is whether you require access to supercomputers, local workstations or state of the art mass spectrometers. In addition to the department facilities, the University library and e-resources provide access to archived and recent research journals. Research facilities are also available across the Maths, Physical and Life Sciences division and take advantage of strong links with the local DIAMOND synchrotron high energy light source and Oxford University Museum of Natural History.
Underlying support for all research groups within the department includes facilities for preparing thin and polished rock sections; IT support; a well-equipped machine shop; computer laboratory; SEM and FEG-SEM and a dedicated departmental library. You will have your own desk within a shared graduate student office and access to breakout rooms for small group meetings. With other graduate students, you will organise you own seminar program and also attend the department’s informal and formal seminar series. You will also have access to the Research Common Room (RCR) where they organise Friday ‘happy hour’ and other social events, but also during coffee and lunch have the opportunity to meet and mingle with postdocs and faculty from across all research areas in the department.
Supervision
The allocation of graduate supervision for this course is the responsibility of the Department of Earth Sciences 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 Earth Sciences.
You will have at least two (and sometimes more) supervisors, who are experts in their field, and who provide the project research framework, guidance and mentoring throughout the program.
You will have the opportunity to meet individually with your lead supervisor and have meetings with any member of the supervisory team to discuss your project.
Assessment
All students will be initially admitted to the status of Probationer Research Student (PRS). Within a maximum of four terms as a PRS student you will be expected to apply for transfer of status from Probationer Research Student to DPhil status.
A successful transfer of status from PRS to DPhil status will require the submission of written work. Students who are successful at transfer will also be expected to apply for and gain confirmation of DPhil status within nine terms of admission, to show that your work continues to be on track.
Both milestones normally involve a presentation and an interview with two assessors (other than your supervisor) and therefore provide important experience for the final oral examination.
You will be expected to submit a substantial/original thesis not exceeding 250 pages after three or, at most, four years from the date of admission. To be successfully awarded a DPhil in Earth Sciences you will need to defend your thesis orally (viva voce) in front of two appointed examiners.
Graduate destinations
Many graduates choose to stay in academia. Others go on to environmental work or work in industry. The Department of Earth Sciences has an active and vibrant alumni network. With an annual newsletter, alumni dinners, networking and other events throughout the year, there are many different opportunities to keep in contact with the department.
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.

Earth Sciences
The Earth sciences are the focus of scientific understanding about this and other planets, embracing a wide range of fundamental topics.
Topics studied in Earth sciences include the evolution of life, how climate has changed and will change in future, the nature of planetary surfaces and interiors, and the processes underlying natural hazards like earthquakes and volcanoes.
The emphasis of both teaching and research in the department is on understanding the fundamental principles of geological processes. Theory, measurements, experiments, and observation of natural processes are all essential elements in the Earth sciences, and students with a strong background in all aspects of the physical sciences are encouraged to join the department.
The department offers the latest analytical equipment and powerful computing facilities, supporting research in all aspects of the Earth sciences.
The department’s research is grouped into six areas of focus:
- geophysics and geodynamics
- planetary evolution and materials
- oceanography, climate and paleoenvironment
- paleobiology and evolution
- geodesy, tectonics, volcanology and related hazards
- Earth resources.
It is not unusual for research topics to be multidisciplinary, and for students to have more than one supervisor covering different aspects of the project.
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.

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
Many projects have associated costs such as field work, computing, consumables and laboratory costs. These are usually covered by scholarships advertised by the Department of Earth Sciences, but not always covered by scholarships the students may have been awarded from elsewhere. Students will need to establish with their supervisor whether they have funding available to cover any such costs.
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.
