Charlie Lees' Research Group: Transformative IBD Medicine

Predict • Personalise • Prevent inflammatory bowel disease (IBD)

Professor Charlie Lees

Professor of Gastroenterology

Research in a Nutshell

We build data‑driven tools that predict disease course and personalise therapy in IBD. Our work integrates longitudinal biomarkers and EHR data with multi‑omics, digital telemonitoring, and machine learning to forecast flares, guide treatment choices, and reduce complications. The practical end‑point is a clinically embedded decision support tool for frontline care.

Why Edinburgh / IGC?

Edinburgh uniquely couples world‑class data science and statistical genomics at the Institute of Genetics and Cancer with one of the world’s most complete IBD real‑world cohorts in NHS Lothian, allowing rapid translation from discovery to clinical implementation. We build on two decades of IBD genetics and epidemiology leadership in Edinburgh and across international consortia, now extending that tradition into dynamic prediction and service redesign. Our clinical data is being integrated with DataLoch and TrakCare to surface real‑time risk and action prompts in routine care.

Principal Investigator (brief)

Prof Charlie W. Lees Professor of Gastroenterology (University of Edinburgh) and Consultant Gastroenterologist (Edinburgh IBD Unit). Trained in London (UCL MBBS, 2000), moved to Edinburgh in 2001 for medical and gastroenterology training, PhD in IBD genetics (2009), NHS Consultant since 2009, and UKRI Future Leaders Fellow since 2019. Charlie maintains a large, complex IBD clinic while leading a translational research team focused on prediction, prevention and practical care impact.

What we’re Working on

Core research themes

  • Dynamic risk prediction: using longitudinal faecal calprotectin (FC), CRP and multimodal biomarkers to anticipate flares and complications before symptoms escalate.
  • Therapy positioning & outcomes: comparative effectiveness, optimal sequencing and persistence of advanced therapies using high‑quality real‑world data across Lothian and partner centres.
  • Global epidemiology & burden: mapping how IBD is evolving locally and worldwide, alongside implications for policy and health‑systems.
  • Environment, diet, microbiome, genetics & flare biology: Leveraging the PREdiCCt study cohort’s deep baseline phenotyping and longitudinal follow‑up to better understand disease triggers and modifiers.

Major studies & data resources

  • PREdiCCt (PRognostic effect of Environmental factors in Crohn’s & Colitis): UK‑wide prospective cohort, 2,629 participants across 49 sites; deep diet, environment, microbiome and psychosocial phenotyping; now building prediction models that combine baseline and longitudinal data.
  • Lothian IBD Registry: comprehensive longitudinal EHR cohort (≈10,000 patients) with 20+ years of data; platform for biomarker modelling, pharmaco‑epidemiology and service evaluation; integrated with DataLoch to enable embedded decision support. Linked biobank available for collaborative studies.
  • SENTINEL: AI-driven dynamic clinical decision support tool built to transform IBD care in Lothian and scale; test-bed for risk prediction models developed by our data science team using landmarking survival analysis with latent-class mixed models

Strategic collaborations

  • Biomedical Data Science (MRC HGU): with Dr Catalina A. Vallejos: statistical genomics, EHR modelling, and shared methods pipelines (co‑supervised researchers).
  • PREDICT Center, Denmark (Aalborg University): with Prof Tine Jess: large‑scale phenomics and risk prediction; Charlie is Adjunct Professor at PREDICT.

National & international consortia

UKIBD BioResource; IIBDGC; PANTS; GIVES‑21; and the Lancet Commission on Global IBD (2024–2026). These programmes extend our genetics, pharmaco‑genetics, epidemiology, and outcomes work across global networks.

Impact & Translation

We prioritise improving clinical care translating models into embedded decision support with nurse‑led triage prompts, treat‑to‑target nudges, and population dashboards, monitored for calibration, drift and fairness. Our near‑term target is a pilot across high‑risk patients in Lothian, scaling to service‑wide adoption with measurable reductions in IBD bed‑days and improved flare‑free survival.

Future Directions

  • AI‑powered clinical decision support (SENTINEL): live, explainable risk and action prompts in the EHR (clinician‑in‑the‑loop), expanding to SaMD as evidence matures.
  • Next‑gen multimodal models: integrate wearables, home FCP, metabolomics (Nightingale), microbiome and polygenic scores for personalised trajectories.
  • Global equity & implementation: adapt models to varied health‑system contexts via federated analytics and pragmatic datasets.
