How can mathematics help us understand the dynamics of infectious diseases? Or how an idea circulates on social media? Or the behaviour of queues? We’ll show you how mathematics solves real-world problems. You’ll work with experts whose research is having an impact – from forecasting local outbreaks of COVID, to predicting floods.
In your first year, you’ll explore the basics of mathematics. This includes analysis and linear algebra, as well as an introduction to computational mathematics. In your second year, you’ll add probability and statistics. In your final year, you then build on your existing knowledge and discover new aspects of the subject, including:
- mathematical biology
- cryptography
- financial mathematics
- partial differential equations.
This course is flexible, so you can focus on what fascinates you while gaining a strong foundation in core mathematics. You’ll develop your analytical and modelling skills using industry-standard software such as MATLAB, Python and R.
Our Department is a close-knit community, and you’ll get to know your lecturers on an individual basis. Their dedication and support will help you to get the most from your degree. Academic advisers support you every step of the way and you’ll have lots of opportunities to engage with potential employers. You’ll also have a dedicated careers advisor.
During your studies, you’ll develop the knowledge and skills employers want. You’ll gain experience in analysing large data sets, problem solving, coding, and team working. You’ll also have the opportunity to apply for a placement, where you can gain experience working with a company. Our graduates have gone to work in roles such as:
- business analyst
- data engineer
- associate auditor
- software developer
- game designer
- statistician.
Accreditation
- This programme will meet the educational requirements of the Chartered Mathematician designation, awarded by the Institute of Mathematics and its Applications, when it is followed by subsequent training and experience in employment to obtain equivalent competences to those specified by the Quality Assurance Agency (QAA) for taught masters degrees.
We understand that deciding where and what to study is a very important decision. We鈥檒l make all reasonable efforts to provide you with the courses, services and facilities described in this prospectus. However, if we need to make material changes, for example due to government or regulatory requirements, or unanticipated staff changes, we鈥檒l let you know as soon as possible.
MMath or BSc?
We also offer this course as a four-year MMath, or as a four-year MMath with research placements.

We regularly review our modules to incorporate student feedback, staff expertise, as well as the latest research and teaching methodology. We’re planning to run these modules in the academic year 2025/26. However, there may be changes to these modules in response to feedback, staff availability, student demand or updates to our curriculum. We’ll make sure to let you know of any material changes to modules at the earliest opportunity.
We’ll do our best to provide as much optional choice as we can, but timetabling constraints mean it may not be possible to take some module combinations. The structure of a small number of courses means that the order of modules or the streams you choose may determine whether modules are core or optional. This means that your core modules or options may differ from what’s shown here.
