Graeme F. Fowler, Ph.D., P.E.
Principal Engineer
Vehicle Engineering
  • Phoenix

Dr. Fowler specializes in issues related to both on-road and off-road vehicles, including handing and stability, component evaluation and testing, accident reconstruction, crash testing, patents, and risk analysis. Dr. Fowler has experience working on automobiles, light trucks/SUVs, on- and off-road motorcycles, All-Terrain Vehicles (ATVs), Recreational Off-Highway Vehicles (ROVs) or side-by-sides, golf carts and construction/industrial equipment.

While at Exponent, Dr. Fowler has gained extensive experience operating, testing and evaluating ATVs and side-by-sides focusing on handling and stability, general operation, analysis of accident records and data, comparative risk analysis and accident reconstruction. Dr. Fowler has evaluated proposed design modifications for ATVs, conducted instrumented testing of off-road motorcycles to investigate vehicle loading and component performance, and has experience analyzing computer simulations aimed at modeling off-road vehicle dynamic behavior.

Dr. Fowler also has experience reconstructing passenger vehicle rollover crashes and analyzing the causes of loss of control through vehicle testing, analysis of crash data files and, review of driver performance data and literature. At Exponent, he has been involved with rollover crash tests and conducted vehicle handling and stability test programs utilizing standardized procedures or specialized tests to evaluate case-specific circumstances. In addition, Dr. Fowler has experience both using and analyzing computer software for vehicle dynamics and accident reconstruction.

Prior to his work with Exponent, Dr. Fowler was a Junior Lecturer at the University of Auckland, New Zealand.
