He has served as the lead investigator on projects to determine the epidemiology and outcome of mild TBI (K23 from NINDS), to image with DTI axonal injury acutely after mild TBI (R01 from NICHD), to determine the role of serum S100B in the diagnosis of intracranial hemorrhage after mild TBI (New York State Department of Health), and to validate new putative markers of axonal injury after sports-related concussion (K24 NICHD). Most recently Bazarian was the PI on a study using diffusion tensor imagine and football helmet impact sensors to investigate the natural history of white matter damage after multiple sub-concussive head blows (NFL-Charities). In 2010, Bazarian joined the University of Rochester Sports Concussion Clinic, providing outpatient concussion care to area high and collegiate athletes.
