My research is focused on translation of advanced, quantitative MRI methods to the human population at both high and low field strenghts.  Specifically, I am interested in developing advanced quantitative MRI methods to study under-represented structures of the human nervous system (optic nerve, spinal cord, and peripheral nerves) as they pertain to human disease.

We are currently involved in a number of research projects, all of which are targeted at understanding the pathophysiology of human disease through the development of advanced, quantitative MRI biomarkers for neurological diseases of the Brain, Spinal Cord, Optic Nerves, and Peripheral nerves.  Specifically, we are focused on ultra-high field (7T) CEST, Diffusion (conventional diffusion tensor and advanced diffusion weighted MRI), Magnetization Transfer, and quantiative T2.
