Key facts

Mode of study Full-time, part-time
Qualification PhD, MPhil
Full-time duration PhD 3.5 years; MPhil 1 year
Part-time duration PhD 5 years; MPhil 2 years
Start dates January, April, July, October

As a research student, in the first and second year you will follow an agreed programme of lectures and reading courses agreed with your supervisor to introduce you to research skills and methods, and to advance your knowledge in your chosen field. These include formal assessment.

This includes a broad choice of postgraduate courses provided through the national collaborative networks:

  • MAGIC (for pure/applied mathematics)
  • NATCOR (for operational research)
  • APTS (for statistics).

Regular seminars in all subject areas, as well as the Cardiff Mathematics Colloquia and the yearly Welsh Mathematics Colloquium, provide insight into cutting-edge research.

Moreover, research students benefit from a carefully developed graduate program including computational, presentational and subject-specific skills.

Students will also write a substantial end-of-year report and give a seminar in the department.

The PhD programme leads the student, through taught courses and individual project supervision, to the frontier of an area of mathematics, with the aim of creating a piece of original research, written up in the doctoral thesis. In the process, the student acquires essential research, problem-solving and communication skills. The MPhil programme is similar, but less ambitious due to its more limited scope; work on an MPhil can lead on to completing a PhD.

Skills developed

In addition to in-depth knowledge of a mathematical research area, PhD students gain general research and presentation skills, and (optionally) undergraduate teaching skills, HEA accreditation possible.

The School of Mathematics offers an exceptionally wide range of opportunities for postgraduate studies in mathematics. The academic staff are engaged in research projects in fields that are as varied as number theory, functional analysis and spectral theory in pure mathematics, image processing, operational research, statistics and quantum field theory.

Many research projects undertaken by members of staff in the School are being generously funded by the public and private sectors. The leader of the Operator Algebras and Non-Commutative Geometry group is the co-ordinator of the European Network on Non-Commutative Geometry funded by the EU TMR programme. Other sources of funding include EPSRC, Leverhulme Trust, NATO, INTAS, Ministry of Defence, Wellcome Trust, GlaxoSmithKline, Proctor and Gamble.

We have close links with several universities and institutions abroad. These include the Institute of Advanced Study in Princeton, the Australian National University and the Australian Road Research Board in Melbourne, Ecole Superieure d'Electricite in Gif-Sur Yvette, ETH in Zurich and universities in Canada, the Czech Republic, France, Germany, Italy, Ireland, Norway, Saudi Arabia, Japan, Malaysia and USA.

Research environment

The individual research groups run weekly seminars with guest speakers, and postgraduate research students regularly attend the seminar in their research area, and are encouraged to profit from talks in other areas, too. We organise about three mathematics colloquia with distinguished guest speakers per term.

Moreover, Cardiff is the venue for a number of international workshops and conferences organised by members of the School , thus giving postgraduate students a welcome opportunity to learn about world-leading current research. They are also encouraged to take part and present their results at major conferences in the UK and abroad.

At the annual Welsh Mathematics Colloquium at Gregynog, postgraduate students can showcase their work in the group of Welsh Mathematics departments.
