Research Engineer

Research Engineer specializing in collision analysis, vehicle crash performance evaluations and accident reconstruction. Research activities include vehicle safety system evaluations and development of specialized reconstruction techniques. These studies have utilized instrumented crash tests, vehicle component testing and computer analysis techniques. Lectures and publishes research papers on the subjects of automotive collision safety and collision analysis techniques.

Consulting activities involve accident reconstruction, including evaluation of vehicle and occupant dynamics and kinematics as well as analysis of vehicle crash performance and safety system evaluations. These activities include court appearances as an expert witness.
