Biography

Chris Tomlinson is an Anaesthetics & Intensive Care registrar undertaking a PhD at the UKRI UCL Centre for Doctoral Training in AI-enabled Healthcare Systems.

Combining technical expertise in epidemiology, data science and machine/deep learning with an extensive background in clinical medicine and physiological research he uses real world evidence to uncover new insights of critical relevance to patients, clinicians and policymakers. Most recently this has involved creating novel COVID-19 phenotypes from linked-EHR data of 57 million individuals in England (now published in Lancet Digital Health).

He is interested in the application of AI methodologies to disentangle the complex interactions between organ systems, diseases, individuals and healthcare services to advance our scientific understanding and translate knowledge into tangible benefits to patient care.

Interests

  • Phenomics: Defining clinically-relevant phenotypes at scale to unlock healthcare data for research & patient benefit
  • Representation learning: Harnessing Large Language Models (LLMs) and Graph Neural Networks (GNNs) to build multi-modal, predictive representations that codify both domain knowledge and data-driven insights
  • Uncertainty quantification: for clinical evaluation and scientific discovery, through assessing robustness to distributional shift and performance in inductive learning settings
  • Causal inference: for evidence generation from observational data and to learn better representations
  • Real-world evidence: I prioritise working with routinely-collected healthcare data to ensure my research is of direct relevance to patients, clinicians and policymakers

Projects

NHS DART Internship: Graph Representation Learning
Representation learning for EHR data, exploring graph structures and semantic embeddings applied to national-scale datasets
NHS England Data Science PhD Internships: Project Brief
UCL-GSK Phenomics Hub
Phenotyping at scale across diverse biobank cohorts to power genomic & proteomic analyses for target identification, drug discovery, and precision medicine.
Disease Atlas
Underpinned by the needs of patients, clinicians and researchers, the Disease Atlas is an ambitious project involving the generation of a systematic, data-driven knowledge across all common and rare diseases. Using newly available nationwide data on 56 million people the Atlas is generating novel comparative insights of the health needs of patients, the care provided, and the research that is carried out.
Automated Assessment of Vascular Perfusion (Alan Turing Institute Data Study Group)
Deep-learning based analysis of sidestream dark field (SDF) imaging videos to quanitfy vascular perfusion in ICU patients.
Alan Turing Institute Data Study Group
CVD-COVID-UK/COVID-IMPACT Consortium
Contributing clinical experience, data wrangling and analytical skills to development of COVID-19 Severity phenotypes from linked EHR data for 54 million patients in England.

Collaborators

Chris enjoys productive collaborations spanning computer science, health informatics and clinical medicine across UCL institutions, other universities within the UK, and abroad, as well as organisations such as Health Data Research UK, British Heart Foundation Data Science Centre, The Alan Turing Institute and Wellcome Trust and industry partners such as GSK, Databricks and AWS.

He strongly believes in the value of multidisciplinary collaboration for delivering responsible innovation and impacts, particularly in complex areas such as healthcare and biomedicine, as well as relishing the learning opportunities that this provides.

This ethos is reflected in a wide range of co-authors, as visualised in the interactive network diagram below:

Hospital admissions linked to SARS-CoV-2 infection in children and adolescents: cohort study of 3.2 million first ascertained infections in England

For July’s BHF Data Science Centre webinar we were joined by Professor Kate Brown from Great Ormond Street Hospital (GOSH) and Dr Chris Tomlinson from University College London (UCL). They speak about findings from a recent paper, published on 5th July 2023, outlining the impact of COVID-19 on children across England. This study - undertaken as part of the BHF Data Science Centre CVD-COVID-UK/COVID-IMPACT Consortium – looked at 12 million childhood health records across England during the height of the pandemic, and analysed 3.2 million cases of coronavirus infection. The study reveals the extent of severe outcomes in children during the pandemic and could inform public health policies.
