Summary

 

Summary

I am a Senior Image Processing and Data Scientist based at the Cardiovascular Magnetic Resonance unit, Royal Brompton Hospital. I have a background in Physics and Mathematics, a PhD in MRI Physics (Imperial College :: London), and an extensive experience in MRI research.

Since 2012, I have been working closely with a team of physicists and clinicians in diffusion tensor cardiovascular magnetic resonance (DT-CMR). It is a novel technique for the investigation of the 3-dimensional microstructure of the heart in-vivo. We aim to improve the understanding of how the healthy heart functions as well as how microstructural dysfunction contributes to disease.

I am focused on creating specialised tools to perform data analysis, image processing, and data visualisation, with a recent interest in finding solutions with AI.


Left ventricle tractography


Highlights



We developed and validated a fully automated postprocessing framework for in vivo diffusion tensor cardiac magnetic resonance (DT-CMR) data powered by deep learning semantic segmentation (TensorFlow):

  • U-Net architecture
  • Proposed fully automated post-processing pipeline


We published in vivo studies showing that secondary directions of diffusion align with the laminar organisation of cardiomyocytes in the heart, and that cardiomyopathy hearts present impaired mobility:

sheetlet rotation
