Abstract

My work consists of basic science, engineering and translational science as all three components involve MR. My basic science focuses on the understanding of MR frequency signal created by biological tissue. The engineering component deals with the improvement and development of existing and novel MRI methods (e.g. fast myelin water imaging, susceptibility weighted imaging with multiple echoes, an improved scan for the detection of multiple sclerosis lesions). Finally, I use these methods for my own biomedical research on multiple sclerosis (MS) and mild traumatic brain injury. I collaborate with researchers from various departments (Psychiatry, Neurology, Pediatrics, ICORD, Physics and Astronomy) to investigate conditions including first episode of mania, stroke, Alzheimer’s disease, Parkinson’s disease, and spinal cord injury.
