• Provided reports, deposition testimony, litigation support, and trial testimony as needed.
• Testimony in state and federal courts
• Testimony in International Trade Commission hearing concerning patent infringement
• Provided analyses of aerodynamics, dynamics, performance, stability and control, control systems, structural components, propellers, and engines of airplanes and helicopters.
• Provided analyses of the operation, dynamics and control of Segway Human Transporters, automobiles, up-enders, weight machines, and other products.
