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 Department of Computer Science, 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 other departments, with links to 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 collaborative with industrial partners. We strive to excel in our research, with many members of staff publicly recognised as experts in their respective fields.
The recent Research Excellence Framework (REF) 2021 puts 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%) or internationally excellent. 100 per cent of our computer science postgraduate research students go on to employment or further study (Graduate Outcomes survey 2022, HESA).
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 for 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 Department, 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 activities within our Department, including monthly tea parties between PhD students and staff, elevator pitch sessions every other month, and bespoke workshops and social events.
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.
The professional development of postgraduate researchers is supported by the Doctoral College, which provides training in essential skills through its Researcher Development Programme of workshops, mentoring and coaching. A dedicated postgraduate Careers and Employability team will help you prepare for a successful career after the completion of your PhD.
