Why choose this course

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 EngineeringBiomedical SciencesPsychologyBusinessSociology 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. With EIT Digital, we have established a Centre for Doctoral Training in Future Connected Technologies focusing on applied research in cyber security, artificial intelligence and communications. 

We strive to excel in our research, with many members of staff publicly recognised as experts in their respective fields.  

In the most recent Research Excellence Framework (REF) in 2014, 60 per cent of our research was rated world-leading or internationally excellent, and our research profile has been consistently ranked in the world top 150 and top 10 in the UK, according to academic subject rankings of SJTU Academic Ranking of World Universities (ARWU) in Computer Science.

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 during your PhD. 

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. 

Research support

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.
