Machine learning and data science are all around us. The need for people who can collate and interpret complex data has never been greater. This course will give you the skills to solve data-intensive problems.
You’ll explore the relationships between mathematics, data and statistics and gain a thorough grounding in theories and techniques. You’ll apply mathematical algorithms for the analysis, interpretation and visualisation of large data-sets, using real-world data.
In your mathematics modules you’ll learn the theory that forms the basis of modern data science. You’ll put this theory into practice in your data science modules. Our faculty are experts in this exciting field. Their research is having significant impact in areas such as:
- artificial intelligence
- social networks
- infectious disease control.
You’ll develop your analytical and modelling skills, using industry-standard software such as Python and R.
By graduation you’ll have gained the skills, and confidence, to become a capable quantitative scientist. Career options include roles in:
- the financial services
- information and digital technology
- research.
Our Department is a close-knit community. You’ll get to know your lecturers and their dedication and support will help you get the most from your degree. Academic advisers also 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.
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.

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.
