Personal profile
Research
My research focuses on improving measurements of blood flow using magnetic resonance imaging (MRI). The work is performed in the exciting intersection of advanced technical development and clinical patient examinations.
Research areas include:
- Volumetric "one-click" MRI to measure flow in all vessels of interest in the patient in a single scan.
- Motion estimation and correction to enable use of MRI during physical exercise.
- Advanced physical models to improve accuracy, precision and scan time.
- Imaging with simulations of flow (CFD) and MRI physics "in the loop"
- Validation of flow measurements in challenging clinical situations using "phantom" models
