Expert has performed investigations and reconstructions of high and low-speed motor vehicle accidents involving passenger cars, motorcycles, pedestrians, bicycles, and commercial vehicles. His experience includes the use of conservation of energy and conservation of momentum analysis to determine the speed of vehicles involved in accidents, crashworthiness of vehicles, occupant compartment intrusion, driver reaction, and time/space relationships and analysis. Expert’s investigations often involve analysis of vehicle dynamics, vehicle safety, human factors and visibility studies. Frequent aspects of these investigations also involve the evaluation of the performance of brakes, tires, seat belts, and airbags. He also has working experience with engine, drivetrain and suspension failure analysis. Expert has also employed reconstruction techniques to analyze injury incidents and industrial accidents.


Expert frequently utilizes the latest technologies available in accident reconstruction throughout all analysis stages, from gathering evidence through accident reconstruction and accident simulation. As a technician certified in Bosch crash data retrieval, Expert has retrieved and analyzed crash data from electronic data recorders in numerous passenger vehicles. In addition, Expert frequently surveys accident sites and vehicles using high definition 3- D laser scanning, total stations, and/or photogrammetry. After gathering survey data, Expert uses computer-aided drafting software packages to view the evidence and gather detailed measurements in virtual space. During the reconstruction process, Expert frequently develops and utilizes advanced computer scripts to solve complex and/or iterative calculations. After reconstructing an accident, Expert often simulates the accident using advanced crash simulation software, PC-Crash.


Expert has been involved in extensive investigation and analysis of the safety of mechanical products. Expert has applied the principles of

safety engineering to the investigation of accidents in the areas of consumer products, window covering products, and material handling equipment such as stand-up and sit-down forklifts, racking systems, and warehouses. Expert has also been involved in liability investigation involving construction equipment such as cranes, aerial lifts, front loaders, motor graders, skid steers and various other pieces of equipment. Expert has also been involved in liability investigation involving heavy machinery, such as wood chippers and material bailing equipment. Frequent aspects of these investigations include maintenance, safety engineering, human factors, and incident reconstruction. Expert is fluent in the safety engineering aspects of CFR, FMVSS, ANSI, ASME, SAE, and other standards applicable in product cases.
