My primary research goals is to develop new methods to quantify the underlying structural composition and metabolic activity in the nervous system. I am currently investigating a MRI sequence called chemical exchange saturation transfer (CEST). CEST sequences can image the underlying metabolic activity in a tissue without the need for extraneous contrast. My aim is to develop these techniques at 7T in order to image glutamate in post-stroke patients in vivo to determine how these levels change following a stroke.
