Dr. O'Shea is proficient in vehicle dynamics analysis, including computational mechanics and the programming and use of computer simulations. He specializes in the investigation and reconstruction of vehicle accidents, including events involving heavy trucks, passenger cars and rail vehicles.
Dr. O'Shea completed his Doctor of Philosophy in Mechanical Engineering at the University of Illinois at Chicago (UIC), where his area of focus was in multibody system dynamics. At UIC, he applied his education, training and experience in dynamic systems to stability analysis and failure prevention of rail cars.
Prior to joining Exponent, Dr. O'Shea was a researcher at the UIC Dynamic Simulation Laboratory, and also worked at a multibody system software development and consulting firm. His prior work and research involved the design, development, testing, and optimization of physics-based simulation software.
