Our research interests focus on developing and applying quantitative MRI methods to study various diseases, including multiple sclerosis (MS), schizophrenia & bipolar disorder, traumatic brain injury (TBI), Alzheimer's disease (AD) and cancer. We have developed a method to correct physiological fluctuation induced artifacts. This method has been successfully applied to improve the quality of many imaging techniques, including susceptibility weighted imaging (SWI), quantitative susceptibility mapping (QSM) and gradient echo plural contrast imaging (GEPCI). We also developed and validated a quantitative MRI technique – simultaneous multi-angular relaxometry of tissue with magnetic resonance imaging (SMART MRI), which provides multiple quantitative relaxometry measurements. Our recent projects include using quantitative GEPCI technique to study multiple sclerosis and developing a B1 mapping technique for SMART MRI.
