Collapse Overview 
Collapse overview
The goals of my research are to advance the understanding of central nervous system (CNS) diseases through the application of advanced neuroimaging techniques, specifically, magnetic resonance imaging (MRI) and MR spectroscopy MRS.
Currently, am active in a number of research projects related to brain tumors, hypoxic ischemic injury in neonates, neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), and neuro-developmental disorders such as autism or OCD.
