BLAST-INDUCED TRAUMATIC BRAIN INJURY

Blast-induced Traumatic Brain Injury

To date, there is no consensus on whether or how exposure to blast waves (i.e., exposure to blast overpressure) causes mild traumatic brain injury. Without such an understanding, we cannot develop effective strategies that prevent, or provide protection against, this type of injury. We perform experimental studies to support the development and validation of high-fidelity finite-element biomechanical models, through which we investigate and quantify the effects of various potential mechanisms of blast-induced traumatic brain injury.
