My primary research interest is to develop novel imaging methods to deepen our understanding on pathophysiology and improve clinical diagnosis and patient management. I have focused on MR imaging and combined PET/MR imaging. My expertise are in MR physics, MR pulse sequence design and programming, image reconstruction, data processing and statistical analysis.

I have extensive experience in MR oxygen metabolic imaging, perfusion (Dynamic Susceptibility Contrast and Arterial Spin Labeling) imaging, susceptibility weighted imaging (SWI), diffusion tensor imaging (DTI)/HARDI, phase contrast imaging, MR spectroscopy, quantitative T1 and T2 measurements, and attenuation and motion correction for simultaneous PET/MR measurements. We have applied novel imaging techniques to study cerebrovascular disease, sickle cell disease and tumor.
