Charles Crosby, P.E.
Senior Engineer
Vehicle Engineering
  • Phoenix

Mr. Crosby's areas of expertise include accident reconstruction and vehicle crash analysis, and he has worked in these fields since receiving his B.S. in Mechanical Engineering in 2006. Mr. Crosby has worked on the analysis and reconstruction of a variety of motor vehicles from motorcycles and passenger cars to light and heavy trucks. He is experienced in the evaluation of vehicle simulation and accident reconstruction computer software. His research and publications include crash pulse analysis, methods to determine the forces required to produce gouging on roadway surfaces, and steel bollard impact energy.

Mr. Crosby has training and experience in the imaging, evaluation, and use of event data recorder (EDR) data. This includes data retrievable from airbag control modules (ACM), powertrain control modules (PCM), and heavy truck/commercial truck electronic control modules (ECM). Mr. Crosby provides engineering consulting and support to clients through vehicle and site inspections, 3D scanning, and photogrammetric evaluations. Additionally, Mr. Crosby’s testing activities include full scale crash testing, such as barrier impact testing, inverted drop testing, and rollover testing, as well as vehicle component assessments including suspension failure testing, and roof crush evaluations.
