I have 30 years of experience, and specialize in the field of engineering design with specific knowledge in the areas of machinery, occupant restraint systems and failure analysis. I have published on such topics as seat and restraint design and failure analysis, aircraft accident reconstruction and occupant restraint systems. I have testified 30 times on topics such as failure of safety systems, automotive collision reconstruction and occupant restraint systems. Member of a team comprised of industry experts that analyzed passenger injury and seat performance in commercial airline crashes which resulted in a rule change which now requires that stronger 16G seats be installed in commercial aircraft. This has resulted in the documented improved survivability of commercial aircraft crashes.
