Her research addresses challenges in spinal cord MRI caused by physiological magnetic field perturbations from breathing and static susceptibility effects. Key contributions include:

• Gradient system characterization
• Dynamic shimming methodologies
• Prospective/retrospective B0 fluctuation correction
• Development of high-resolution imaging protocols
• Optimization of functional MRI sensitivity

Recent publications demonstrate expertise in:

• Spiral imaging reconstruction algorithms
• HiHi fMRI techniques
• Spinal cord functional connectivity reliability
• Signal-to-noise ratio optimization
• Automated z-shimming implementations
• Multicenter protocol comparisons

Teaching responsibilities include advanced MRI courses and core physics subjects:
