Research Interests
Diffusion MR imaging is being widely used for studying the diseases of the central nervous system (CNS). My research has been focused on the applications of diffusion MRI to investigate WM injuries in CNS, and I have been involved in a wide range of methodology developments and clinical applications on brain, spinal cord and optic nerve. This has encompassed development and implementation of novel acquisition methods and MR sequences; imaging protocol design for fast and high-resolution MR imaging; implementation of MR image post-processing pipeline. Applications include spinal cord injury (SCI), multiple sclerosis, traumatic brain injury and stroke.
