Expert Witness Profile

Mr. Bonsall joined Momentum Engineering Corp. in 2015. Prior to joining Momentum Engineering, he worked at an aftermarket automotive parts manufacturer conducting failure analysis and quality control. He has since flourished in the reconstruction and recreation of traffic accidents involving heavy trucks, buses, passenger cars, wheelchairs, scooters, bicycles, pedestrians, and many other modes of transportation.

Since joining Momentum Engineering, Mr. Bonsall has been immersed in the minute details of reconstructing accidents, inspecting vehicles and sites, virtually recreating accidents using software packages such as PC-Crash, visually recreating incidents with help from graphics and animation, and acquiring various certifications to assist in his reconstructions. His breadth of automotive knowledge and new outlook on problem solving are a welcome change to the industry. Mr. Bonsall has testified in trial, deposition, and binding arbitration numerous times while having inspected thousands of vehicles and hundreds of sites within hours of the incident to years afterward.

Mr. Bonsall earned a Bachelor of Science in Mechanical Engineering with an Automotive Engineering concentration from California State University, Northridge in 2015. During his time in school, he was able to become involved with many projects such as the Formula SAE racecar. He was also trained in vehicle dynamics, internal combustion engines, automotive powertrains, and suspension design. He is currently a graduate student at California State University, Long Beach where he will earn his Master of Science in Mechanical Engineering concentrating in Controls, Dynamics, Vibrations, and Robotics.
