Two labs · one pipeline

Cardio AI Lab

We run two complementary spaces — a Computer Lab and a Bioscience Lab — to build interpretable, clinically useful models for cardiovascular health. Our flagship project is CardioFlowFormer, a spatiotemporal framework for motion phenotyping and early risk detection.

Our Labs

Bench and benchmark, in the same loop

Cells are imaged next door to where the models are trained, so a labelling problem at the microscope reaches the pipeline the same week it appears.

Computer Lab

Computer Lab

  • Transformer pipelines for imaging, EHR, and genomics
  • Survival analysis, calibration, and uncertainty
  • Bias audits, domain adaptation, fairness metrics
  • GPU training, MLOps, and reproducible evaluation

Bioscience Lab

Bioscience Lab

  • iPSC-derived cardiomyocyte imaging and annotations
  • Optical flow capture and motion signatures
  • Quality control, lab protocols, dataset curation
  • Bench-to-model feedback for clinically relevant labels

Flagship model

CardioFlowFormer

Transformer-based spatiotemporal model that fuses motion fields, morphology, and temporal contraction metrics to detect ageing- and damage-related cardiomyocyte dysfunction early.

  • Optical flow tokens + temporal attention
  • Explainability with attention maps, IG, SHAP
  • Time-to-event extensions for prognosis
  • External validation on UK Biobank / CPRD cohorts

How it works

From a beating cell to a risk score

Four stages, each one auditable on its own. The motion field and the attention weights are kept, so a prediction can be traced back to the frames that produced it.

  1. Step 01

    Live-cell imaging

    iPSC-derived cardiomyocytes are filmed beating in culture, with annotations made at the microscope.

  2. Step 02

    Optical-flow field

    Frame-to-frame displacement is estimated across the cell, turning contraction into a dense motion field.

  3. Step 03

    Spatiotemporal attention

    Flow patches become tokens; temporal attention weighs which regions and which beats carry the signal.

  4. Step 04

    Risk and prognosis

    Motion phenotypes feed calibrated time-to-event models, with attention maps retained for inspection.
