I am an Associate Professor in the Advanced Imaging Research Center at UT Southwestern Medical Center. My expertise is in developing novel quantitative MRI techniques and analysis methods on the CNS system and musculoskeletal system. I have developed and implemented a 3D under-sampling strategy and sparse reconstruction for diffusion MRI at microscopic resolution. I have successfully pushed the spatial resolution of diffusion MRI close to cellular resolution, and this provides a solid technology foundation to investigate the whole brain fiber orientation distributions, connectome, and tissue microstructure. This acceleration also enables high throughput genetic application of MRI technology to various mouse models, including Alzheimer’s disease, autism spectrum disorder, and multiple sclerosis. The high-quality tractography data has been used to validate with the traditional neuronal tracers from Allen Mouse Brain Atlas and Light Sheet Microscopy. I have refined the current algorithms for phase processing by solving the inverse problem of source-field relations to derive quantitative susceptibility mapping (QSM). I have applied this novel technique to different brain diseases, including multiple sclerosis, microbleeds, and calcification.
