Research Associate/Senior Research Associate – Development of Machine Learning Methods for Clinical Trials

Alan Turing Institute London United Kingdom Research Programmes
Warning! Vacancy expired

Company Description

The Alan Turing Institute is the UK’s national institute for data science and artificial intelligence. The Institute is named in honour of the scientist Alan Turing and its mission is to make great leaps in data science and artificial intelligence research in order to change the world for the better.

Position

Clinical trials are the gold standard for testing treatments (drugs, surgical procedures, or other health interventions) in clinical care. Because we rely on trial results for treatment approvals, the UK government has earmark methodological developments in clinical trials as an area where the UK aspires to be world-leading.

The post-holder will explore existing, and develop novel, machine learning methods for two of the challenges faced by clinical trials. These are:

  1. Treatment effect heterogeneity and subgroup discovery: identifying which patients may benefit from treatment. The aim is to use data from large randomised trials to develop novel statistical machine learning methods for the identification of treatment effect heterogeneity in clinical trials, as well as building counterfactual predictive models leading to personalised treatment effects. Retrospective analysis in clinical trials enables the data-driven detection of subgroups of patients who may benefit from a particular course of treatment, thereby providing the basis for future trials.
  2. Improving quality assurance processes. Clinical trials typically involve patients recruited and followed up by multiple sites (usually hospitals). Trial monitoring is a necessary task in all clinical trials where the central trial team assesses performance at each site. Poor performance indicators are aggregated in a pre-specified way; if a threshold is exceeded, the trial team then visits the site to ensure that all applicable ethical and regulatory requirements, guaranteeing participants’ safety and data robustness, are being adhered to. However, currently there is doubt that this process adequately targets sites at risk of non-adherence. The aim of this project is to explore AI / machine learning approaches to identify and predict which sites within an ongoing clinical trial are underperforming or at risk of non-adherence, using centrally held patient-reported data, and previous longitudinal site monitoring data, which includes time-series data and free text. These predictions will assist in the prioritisation and planning of monitoring actions (e.g. site visits).

Particular attention will be paid to issues around interpretability, reproducible research, methods validation and the assessment of false discovery rates.

Successful candidates should have a strong quantitative background and preferably a strong machine learning and statistics background and be eager to do research at the interface of AI and clinical trials.

ORGANISATIONAL POSITION

The postholder will be based at the Alan Turing Institute, and work closely with senior collaborators at the Alan Turing Institute and the MRC Clinical Trials Unit (MRC CTU) at UCL.

The successful candidate will be a key member of the project team, playing a central part in shaping the project, assuming responsibility for its successful delivery, conducting research, and taking primary responsibility for the writing of academic manuscripts, both of novel research and tutorial papers giving guidance to the clinical trial community. These will represent the project’s main deliverables. Other important components of the role include engagement in collaborative and knowledge-sharing activities with other clinical trial researchers and CTUs, and organising activities aimed at communicating project findings to academic and stakeholder audiences.

Depending on the background of the successful candidate, there will be opportunities for undertaking appropriate training in Clinical Trial design, conduct and analysis.

The post holder will:

  • Explore the potential of new statistical machine learning methods to improve the learning opportunities from clinical trials;
  • Undertake analyses using machine learning methods on existing trials data held within the MRC CTU;
  • Present research findings through academic papers and presentations at academic and professional conferences, and to contribute to the external visibility of both institutes;
  • Participate in the organisation of research workshops and other events.

The post holder will be expected to work collaboratively with the senior investigators from across the Turing and MRC CTU as well as with external partners on the project. At the same time, you will be given the personal freedom to develop and pursue innovative research ideas.

BACKGROUND

The Alan Turing Institute in partnership with the MRC Clinical Trials Unit at UCL is offering an exciting job at the interface of machine learning and biostatistics. This is an opportunity for a data scientist, machine learning researcher or statistician with interests both in the development of machine learning methodology and in medical research to join Professor Chris Holmes and Dr Karla Diaz-Ordaz’s causal machine learning research group.

MRC Clinical Trials Unit at UCL (MRC CTU)

The MRC CTU is a centre of excellence for clinical trials, meta-analyses and epidemiological studies. It is committed to strengthening and expanding the evidence base for healthcare nationally and internationally. It also develops methodology to improve the design, conduct and analysis of clinical studies, and hosts one of the MRC’s eight regional Hubs for Trials Methodology Research. The MRC CTU currently employs around 230 staff. Further details can be found at its website: http://www.ctu.mrc.ac.uk/.
