My research interests include RF pulse design for MRI (particularly parallel excitation), MRI for guided interventions (particularly high-intensity focused ultrasound (HIFU) surgery), and more generally fast algorithms, inverse problems, and optimization.


Members of my group are currently working on improving RF system calibrations such as mapping of the RF transmit field, advanced patient-tailored RF pulse designs for mitigating the effects of B1 and B0 field inhomogeneities, improved temperature reconstruction methods for guiding HIFU surgery, and ultrasound autofocusing algorithms using MR imaging feedback.
