PhD Computer Science
Our Computer Science PhD programme offers advanced training and research opportunities in various areas of computer science. It offers rigorous training, opportunities for collaboration, and the chance to make meaningful contributions to advancing technology and knowledge.
Why choose this
programme?
Our PhD research programme provides you with the opportunity to study a wide range of computer science topics. These include technologies and systems for securing online businesses and our lives, technologies inspired by nature for solving complicated real-world problems in areas such as transport and health, and real-world applications of advanced technologies in cyber security and machine learning. Our expert supervisors, highly rated research activities and excellent facilities mean you’ll be a specialist in your field by the time you complete your PhD.
Surrey Centre for Cyber Security (SCCS), led by the School of Computer Science and Electronic Engineering, is one of only 19 Academic Centres of Excellence in Cyber Security Research recognised by the UK government. It is particularly strong in interdisciplinary research with subject areas including electrical and electronic engineering, biomedical sciences, psychology, business, sociology and law. We also have strong ties with global research institutes, such as the University of Oxford, Microsoft Research Cambridge, KU Leuven (Belgium), McMaster University (Canada) and the National Physical Laboratory (NPL) for joint PhD projects.
Many PhD projects are undertaken in collaboration with industrial partners. We strive to excel in our research, with many members of staff publicly recognised as experts in their respective fields.
The Research Excellence Framework (REF) 2021 ranks Surrey 7th in the UK for research outputs in computer science, with 100 per cent of those outputs recognised as either world-leading (57.1 per cent) or internationally excellent. 100 per cent of our computer science postgraduate research students go on to employment or further study (Graduate Outcomes 2024, HESA).
Studentships
Deep learning for automated building damage assessment
Standard stipend (£19,237 p.a. 2024/25 rates); full home or O/S tuition fees (as applicable); a research, training and support grant of up to £3,000 over the project. Funding available for 3.5 years (42 months).
China Scholarship Council - Surrey Awards
Successful candidates will each receive a full tuition and bench fee waiver (if any applicable).CSC will provide each scholarship recipient with a living stipend (incl. medical insurance) as prescribed from time to time by the Chinese Government. CSC will also cover an international roundtrip airfare of economy class between China and the United Kingdom and will provide a one-off visa application fee reimbursement.
What you will study
Our PhD in Computer Science will give you the knowledge, skills and abilities needed for a career in academia, research and development work in industry, and a wide variety of professional opportunities elsewhere.
It normally takes around three to four years to complete a full-time PhD. You’ll be assigned at least two supervisors, a principal and a secondary, who’ll guide you through your studies. You’ll learn how to conduct literature reviews, how to develop your research ideas and verify them with experiments, and how to collaborate and perform interdisciplinary research.
Exactly what your studies will look like will depend on your choice of topic: most of our PhD students conduct their research on computers in the School of Computer Science and Electronic Engineering, but some need access to special hardware in a lab setting. We’ll make sure you’ve got everything you need to conduct your research.
We offer a diverse programme of academic and social activities, including monthly tea parties between PhD students and staff, and bespoke workshops and social events.
Assessment
Your final assessment will be based on the presentation of your research in a written thesis, which will be discussed in a viva examination with at least two examiners. You have the option of preparing your thesis as a monograph (one large volume in chapter form) or in publication format (including chapters written for publication), subject to the approval of your supervisors.
Location
Stag Hill is the University's main campus and where the majority of our courses are taught.
