Dr. Prange addresses issues involving human injury biomechanics and kinematics to assess the severity and mechanism of injury incurred during traumatic events. He has expertise in human injury biomechanics, specializing in head injury tolerance, pediatric biomechanics, and occupant kinematics.

Dr. Prange has evaluated the safety of a variety of different products including helmets, juvenile products, and child restraint systems. He has 20 years of experience addressing questions involving head injuries and the unique aspects of pediatric biomechanics.

Dr. Prange's work includes analysis of injuries occurring in transportation accidents; incidents involving consumer products; and a variety of accidental and inflicted injury scenarios His has extensive expertise in adult and pediatric head and neck injury mechanisms and tolerance. His experience includes investigation of the mechanisms, tolerance, and mitigation of traumatic brain injury including concussion, intracranial bleeding, and diffuse axonal injury.

Dr. Prange has investigated the injury mechanisms and kinematics of children during automotive collisions, accidental falls, use and misuse of various child products, incidents of strangulation and asphyxiation, and child abuse. Dr. Prange has addressed issues of injury risk and product safety involving a variety of products including motorcycle, bicycle, football, and other types of helmets; child products such as cribs, infant carriers, strollers, and furniture; and vehicle child restraint systems including boosters, rear and forward facing seats, and vehicle seatbelts. Dr. Prange also has experience in neck and spine structural and failure properties, biomechanics of shaken baby syndrome, injury mechanisms during falls, injury potential of impacts from falling objects, biological material testing, viscoelastic mechanical properties of tissue, and computational models of injury prediction. Dr. Prange also has unique experience conducting research utilizing pediatric cadaveric specimens to determine pediatric head and neck structural properties and injury tolerances.

Prior to joining Exponent, Dr. Prange was a Senior Research Scientist in the Department of Biomedical Engineering at Duke University and a research assistant in the Injury Biomechanics Laboratory at the University of Pennsylvania.
