Course summary

Develop sound practical and theoretical skills in mathematics and software development, preparing you for roles that involve data analysis, modelling and simulation.

Computer science and mathematics are closely linked. Many of the leading applications of computing are mathematical, and computers are fundamentally logic engines.

This joint degree is for you if you enjoy and excel at computing and want to combine that with a very strong interest in mathematics.

By combining our computer science degree with pure mathematics, probability and statistics, you’ll be prepared for careers in data science relying on a combination of mathematical and computational modelling, such as data analysis and forecasting.

In the first two years, you will study a mix of mathematics and computing units, including computational approaches to finding patterns in data and the generation of computational models. In the second year, you will complete a group project with other students to design and build an interactive application, helping you gain important skills for the professional world. You'll also share lectures with Mathematical Sciences students to study fundamental algebra, statistical modelling, and data analysis.

You can specialise in a particular field through optional units and an individual project, combining your interests in a specific area of numerical computer science and mathematics. You’ll regularly meet with an academic who specialises in your chosen field.
