Chris Tomlinson


Senior Research Fellow in Health Data Science

UCL Institute of Health Informatics

Health Data Research UK


Chris is a curiosity-driven physician scientist with over a decade of experience in healthcare, spanning physiological research and clinical medicine, as well as quantitative methods in epidemiology and machine learning. His work has been featured in top medical journals (Nature Medicine, Circulation, BMJ, Lancet Digital Health) and informed policy at home and abroad.

He is excited about the ability of artificial intelligence to flexibly integrate, structure and summarise insights from both traditional knowledge repositories and observational data, to scalably advance our understanding of health and disease, and enable us to address the fundamental challenges of precision medicine: diagnosis, prognosis and treatment response.


  • Clinical foundation models: Harnessing real-world EHR data, codifying domain knowledge, downstream use for precision medicine, trial emulation and population health, multimodality
  • Real-world evidence: I prioritise working with routinely-collected healthcare data to ensure my research is of direct relevance to patients, clinicians and policymakers
  • Causal inference: for evidence generation from observational data and to learn better representations
  • Uncertainty quantification: for clinical evaluation and scientific discovery, through assessing robustness to distributional shift and performance in inductive learning settings
  • Phenomics: Defining clinically-relevant phenotypes at scale to unlock healthcare data for research & patient benefit

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:
