Mathematics and Computer Science

If you love the beauty, precision, complexity and simplicity of mathematics, and like being challenged, then the Mathematics degree at Swansea University is the course for you.

Our new three-year BSc in Mathematics and Computer Science will focus on the application of mathematical ideas and computational skills to cutting edge real world problems. This is an exciting field with rapid developments in areas such as modelling, graphics, security, data analysis, machine learning and artificial intelligence which are all underpinned by mathematical ideas. Through this degree students will not only learn about the theoretical foundations of such ideas, but also develop the practical skills in programming and problem solving that employers are looking for.

The new £32.5M Computational Foundry building at our Bay Campus gives students access to bespoke study and teaching spaces designed by and for mathematicians and computer scientists.

Our Mathematics Reading Room provides a quiet study space for mathematics students, as well as housing a departmental library of resources for study and research, and our state of the art computer labs include a vision and biometric lab, maker lab, theory lab, cyber security/networking lab, user lab and visualisation suite.

We are ranked: • 3rd in the UK for Student Satisfaction (Complete University Guide 2025) • 7th in the UK (Guardian University 2025) • 13th in the UK for Teaching Quality (Guardian University 2025) • Top 201-250 in the World Computer Science & Mathematics (QS World University Rankings 2025)

Mathematics graduates typically earn salaries 50% higher than the average graduate. Mathematicians are highly sought after in lucrative industries such as the actuarial profession, the financial sector, technology and systems administration Our graduates have recently gained employment at organisations including AXA, British Airways, Deutsche Bank, Shell Research, Health Authorities and Local Government.

Our Computer Science graduates have become Analyst Developers, Business Analysts, Computer Programmers, Electronic Engineers, Graphic Designers, Software Developers and Machine Learning Engineers with companies that include IBM, Google, Disney, Facebook, Microsoft and Sony.
