I am developing and appling quantitative magnetic resonance imaging techniques to extracranial tissues and pathologies. My current research project develops an MRI method with high undersampling to rapidly acquire relaxometry and fat metrics in human thoracic and abdominal anatomies. My work includes elements of MR sequence design, parameter estimation and modeling, as well as physiology.
