About the course
The DPhil in Social Data Science provides an opportunity for students to formulate and address novel research questions at the intersection of the computational and social sciences, supported by the multidisciplinary faculty at the OII, Engineering Science, Statistics, Sociology, Computer Science and other departments across the University of Oxford, as well as by the complementary strengths of the student cohort, who draw upon expertise and experience from across the disciplinary spectrum.
This course is taking part in a continuing pilot programme to improve the selection procedure for graduate applications, in order to ensure that all candidates are evaluated fairly. For this course, the socio-economic data you provide in the application form will be used to contextualise the shortlisting and decision-making processes. For more information see the full details about this pilot.
Students are encouraged to pioneer new approaches to contemporary social problems, exploiting fast expanding possibilities in large-scale data collection, machine learning, and statistical modelling. This degree will train individuals to develop and adapt techniques such as machine learning to analyse large, structured and unstructured, complex datasets in order to improve decision making and answer social science research questions.
Beyond the technical skills, the programme will also provide students with a solid grounding in social science theory and methodology, and reflection on the consequences of the techniques applied. Ordinarily, students will be expected to have training similar to that offered within the MSc in Social Data Science, but gaps may be filled with courses from the MSc curriculum as well as other existing courses at the University.
Over the course of the three to four years, you are expected to produce an important and original piece of scholarship that will make a significant contribution to the dynamic area of Social Data Science. On completion, you will have the qualities and transferable skills necessary to excel in teaching, research, policymaking or business.
The DPhil programme at the Oxford Internet Institute (OII) is also available on a part-time basis. The part-time programme is spread over six to eight years of study and research. The part-time degree offers the flexibility of part-time study with the same high standards and requirements as the full-time DPhil programme. The part-time DPhil also provides an excellent opportunity for professionals in high tech industries to undertake rigorous long-term research that may be relevant to their working life. Please visit the department website for further details on part-time doctoral study or contact the Graduate Studies Assistant.
As a part-time student you will be required to attend seminars, supervision meetings and other obligations in Oxford for a minimum of 30 days each year.Attendance will be required during term-time a minimum of one day each week. There will be limited flexibility in the dates and pattern of attendance, which will normally be determined by the fixed teaching and seminar schedule during term.Attendance may be required outside of term-time on dates to 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 Oxford Internet Institute and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff.
Supervision for the DPhil in Social Data Science spans multiple departments (please see the full list of faculty members eligible to supervise DPhil students for this programme). A supervisor may be found outside the list on the course web page, and co-supervision is also possible.
Students should normally expect to meet with their supervisor around three to four times a term.
The sequence of milestones for a DPhil student are as follows:
- Admission as a Probationer Research Student (PRS)
- Transfer to DPhil status (‘Transfer of Status’)
- Confirmation of DPhil status for DPhil students (‘Confirmation of Status’)
- Submission of thesis
All students will be initially admitted to the status of Probationer Research Student (PRS), during which time you will be required to attend. core foundational courses from the OII’s training programme as directed by the Graduate Studies Committee. 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, and achieve, transfer of status from Probationer Research Student to DPhil status.
A successful transfer of status from PRS to DPhil status will require the student to show that their proposed thesis and treatment represents a viable topic and that their written work and interview show that they have a good knowledge and understanding of the subject. Students are also required to demonstrate satisfactory completion of the foundational courses by this point.
Following successful transfer, students will need to apply for and gain confirmation of DPhil status to show that the work continues to be on track. This will need to be completed within nine terms of admission for full-time students and 18 terms of admission for part-time students.
Both milestones 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 an original thesis of not more than 100,000 words 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 Social Data Science you will need to defend your thesis orally (viva voce) in front of two appointed examiners.
Employers recognise the value of a degree from the University of Oxford, and graduates from our existing programmes have secured excellent positions in industry, government and NGOs. Alumni who have pursued academic careers have taken up research and teaching positions at the University of Oxford, Cornell University, University of Hong Kong, Imperial College London, Durham University, University of New South Wales, Coventry University, University of Leicester, University of Ottawa and Michigan State University. OII DPhil alumni also work in wide-range of organisations including The World Bank, Oxfam, Cisco, McKinsey and Google.
The OII Alumni Wall features interviews from both MSc and DPhil alumni about their time at the Department and career paths after Oxford.
