Health Data Science (EPSRC Centre for Doctoral Training)

About the course

The Oxford EPSRC CDT in Health Data Science offers opportunities for doctoral study in computational statistics, machine learning and data engineering within the context of ethically-responsible health research. 

The Oxford EPSRC Centre for Doctoral Training (CDT) in Health Data Science offers a four-year doctoral programme, beginning with the training year, which consists of two terms of intensive training in core data science principles and techniques followed by a third term where students undertake two 8-week research placements in two of their chosen research areas. It is expected that one of these projects will become the basis of the student’s doctoral research, carried out in the following three years. Taught modules and subsequent research supervision are provided by leading academics from the departments of Computer Science (the host department), Statistics, Engineering Science, the Nuffield Department of Medicine, and the Nuffield Department of Population Health.

The first year taught modules include:

  • Ethics of Health Data Science
  • Introduction to Computational Statistics
  • Modern Statistical Methods
  • Bayesian Modelling
  • Introduction to Machine Learning
  • Machine Learning Topics
  • Deep learning, Databases
  • Data Modelling
  • Process Modelling
  • Data Governance
  • Wearables
  • Medical Image Analysis
  • Epidemiology and Clinical Trials
  • Genetics
  • Infectious Disease Epidemiology
  • Pathogen Evolution and Phylodynamics.

A typical weekly timetable contains morning lectures from 9am to 12pm, followed by an afternoon of practical computational exercises from 1pm until 4pm.

Each term of taught modules concludes with an extended, team-based two-week data challenge where the cohort uses an at-scale data set to address a current health research area. Our data science challenges involve engagement from industry and healthcare partners such as The British Heart Foundation, NVIDIA and exchange students from our partner institutions in Berlin.

The centre is based in the Oxford Big Data Institute. The institute is an analytical hub for multi-disciplinary working at Oxford, connecting world-leading expertise in statistics, computer science, and engineering to data-driven research in medicine and population health. It is also home to the newly established Wellcome Centre for Ethics and Humanities.

The institute houses internationally recognised research groups in genomic medicine, medical image analysis, mobile and sensor data, infectious diseases, large-scale clinical trials, ethical aspects of healthcare delivery and the ethics of health research.

Research groups in partner departments address related challenges in data science: machine learning, knowledge representation, healthcare economics and cyber security.


The allocation of graduate supervision is the responsibility of the Centre for Doctoral Training and it is not always possible to accommodate the preferences of incoming graduate students to work with a particular member of staff.

Each student will benefit from dual supervision for the duration of their research project, with at least one of the two supervisors having a strong background in core data science. Many students will wish to pursue a project in collaboration with a partner organisation: a technology company such as Elsevier, NVIDIA, Perspectum Diagnostics, or Zegami; one of our pharmaceutical partners such as GSK, UCB, or Novartis; other groups such as the NIHR Oxford Biomedical Research Centre or the Cancer Research UK Oxford Centre, as well as the research teams in the Medical Science Division provide unique collaboration opportunities.


Modules are assessed in different ways, though usually through project work. Data Challenges are assessed through group presentations on the final day of the Data Challenge. Research placements are assessed with a written report.  Health Data Ethics is a core part of the curriculum and the doctoral dissertation. During the first year ethics will be assessed by presentation. Students will be asked to provide a short presentation of the ethical issues arising in each of their third term placements.

The Centre for Doctoral Training is based in the Oxford Big Data Institute (BDI), a new purpose-built 7500 square-metre building at the heart of the University's biomedical campus, with dedicated teaching space for classes, workshops, group exercises, and presentations, as well as study space for students during their first year. The Institute has many large and small meeting rooms, a large café, and an open, furnished atrium, affording space for formal and informal interaction with research groups, other programmes, and partner organisations.

Students will have access to a secure research computing infrastructure with 6500 high-memory cores, dedicated GPU resource to support deep learning and image processing, and 13PB of storage. The infrastructure supports containerised processing, and students will be able to push their own applications to cloud infrastructure provided by partner organisations. There is central support for common applications and services, including a JupyterHub server for Jupyter notebooks.

The BDI hosts the clinical informatics and big data activity of the National Institute for Health Research (NIHR) Oxford Biomedical Research Centre (BRC), a substantial programme (£114m) of translational research, delivered by the University in partnership with Oxford University Hospitals (OUH) NHS Foundation Trust (FT). This activity includes the development of a secure data warehousing and analytics infrastructure - a ‘research platform’ - to support the large-scale re-use of routinely-collected clinical data for research purposes.

The platform contains integrated, longitudinal records for two million patients, including data from patient administration, electronic prescribing, laboratory tests, imaging reports, pathology reports, discharge summaries and clinical letters. It also contains historical datasets, including a comprehensive collection of laboratory test data, on a larger patient population, from 1993 to date. Oxford University Hospitals have agreed to provide CDT students with access to the platform, and to extracts of the data, for approved training and research purposes.

The BDI hosts the informatics activity of the UK Biobank, a major national and international resource for health research. The Biobank team are leading the development of tools for the acquisition, processing, analysis, and re-use of data from clinical and online assessments, imaging, sensors, genotyping, and national datasets (including hospital episodes, death, and primary care) for a cohort of 500,000 participants. CDT students will have the opportunity to access the expertise of the team, and to become involved in Biobank-based research.

Oxford is one of six substantive sites for Health Data Research (HDR) UK. The Oxford HDR UK team, based in the BDI, will lead research initiatives on 21st Century Clinical Trials and Enhancing Prospective Cohort Studies. This work will include the development of new methods and tools for phenotyping at scale, including machine learning approaches to the analysis of large, complex clinical datasets. CDT students will have the opportunity to participate in HDR UK activities, including a new joint programme with the Alan Turing Institute.
