Course Summary

The DPhil in Mathematics is an advanced research degree which provides the opportunity to investigate a project in depth and write a thesis which makes a significant contribution in the field. You will gain a wide range of research and other skills as well as in-depth knowledge and expertise in your chosen field, whilst studying in a beautiful, modern setting.

During your study at Oxford, you can share in the excitement of contributing to research in one or more of the many topics studied by Oxford mathematicians. Subject areas cover the entire spectrum of mathematics and the department’s research is conducted in many fields, with subject areas including:

  • algebra (primarily group theory and representation theory)
  • number theory
  • algebraic geometry
  • differential geometry
  • topology
  • complex manifolds
  • global analysis
  • partial differential equations
  • functional analysis
  • stochastic analysis
  • dynamical systems
  • mathematical logic
  • optimisation
  • combinatorial theory
  • quantum theory
  • string theory
  • relativity
  • mathematical biology and ecology
  • mathematical modelling
  • fluid and continuum mechanics
  • mathematical and computational finance
  • numerical analysis
  • history of mathematics
  • mathematics applied to problems in earth sciences, materials science and finance.

You will be asked to outline your research interests when you apply, and will be matched to the most appropriate research group. You will also be invited to suggest a specific supervisor or supervisors, and your preferences will be taken into account in allocating you a supervisor (which will be done before your arrival).

Entry requirements

As a minimum, applicants should hold or be predicted to achieve the equivalent of the following UK qualifications: a first-class undergraduate degree with honours in mathematics or a related discipline. A previous master's degree is not required, though the requirement for a first-class undergraduate degree with honours can be alternatively demonstrated by strong performance in a master's degree. For applicants with a degree from the USA, the minimum GPA sought is 3.7 out of 4.0.
