Overview
I co-lead the MR Engineering Lab, which is part of the Brain Imaging and Analysis Center at Duke University. Our research involves the development of novel magnetic resonance imaging (MRI) coil technologies – in particular integrated parallel reception, excitation, and shimming (iPRES) and integrated radio-frequency/wireless (iRFW) coils – to enable imaging, localized B0 shimming, and/or wireless communication with a single coil, thereby improving the image quality and clinical utility of MRI applications such as functional MRI and diffusion-weighted imaging in the human brain and body. We also develop high-resolution diffusion MRI techniques to investigate the microstructure of the human brain and to detect abnormalities in neurological disorders such as Alzheimer’s disease.
